Web Attack: Test-CGI Directory Listing CVE-1999-0070
Severity:Medium
This attack could pose a moderate security threat. It does not require immediate action.
Description
This signature detects attempts to access the Sample Test CGI program through HTTP.
Additional Information
NCSA HTTPd and comes with a CGI sample shell script, test-cgi, located by default in /cgi-bin.

Severity:High
This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.
Description
This signature detects activities of Trojan.Brisv.A which redirects the client to a malicious link which may download files that could compromise the target computer.
Additional Information
Trojan.Brisv.A is a Trojan horse that infects media files which may cause Windows Media Player to access a malicious URL.
The Trojan horse searches the compromised computer for .asf, .mp2, .mp3, .wma and .wmv files, which it then infects. When opened in Windows Media Player the infected files cause the program to connect to a malicious URL which may result in more malware being downloaded on to the compromised computer.
Infected media files may be downloaded on to the computer through file-sharing programs.
Files infected with Trojan.Brisv.A are detected as Trojan.Brisv.A!inf.
Symantec recommends downloading and running the Trojan.Brisv.A!inf Removal Tool to disinfect the affected media files.
Once executed, the Trojan creates the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\PIMSRV
It modifies the following registry entries:
* HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences\"URLAndExitCommandsEnabled" = "0"
* HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Player\Extensions\.mp3\"Permissions" = "21"
It creates the following mutex so that only one Trojan instance is running in memory:
PIMSRV1
It searches for multimedia files with the following extensions:
* .asf
* .mp2
* .mp3
* .wma
* .wmv
It searches for and converts the following files to the WMA format:
* .mp2
* .mp3
It injects functionality into the multimedia files it finds causing Windows Media Player to access a malicious link when the media player opens the infected file.
The infected files are increased 1,138 bytes in size and are detected as Trojan.Brisv.A!inf.
Affected
Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows Vista, Windows XP

Severity:High
This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.
Description
This signature detects file downloads related to Trojan.Gen.
Additional Information
Trojan.Gen is a generic detection for many individual but varied Trojans for which specific definitions have not been created. A generic detection is used because it protects against many Trojans that share similar characteristics.
Trojan horse programs pose as legitimate programs or files that users may recognize and want to use. They rely on this trick to lure a user into inadvertently running the Trojan. Often a Trojan will mimic a well known legitimate file name or pose as a particular type of file, like a .jpg or .doc file to trick a user.
Distribution of Trojans on to compromised computers occurs in a variety of ways. From email attachments and links to instant messages, drive-by downloads and being dropped by other malicious software. Once installed on the compromised computer, the Trojan begins to perform the predetermined actions that it was designed for.
Affected
Windows
Response
No further action is required but you may wish to perform some of the following actions as a precautionary measure.
• Update your product definitions and perform a full system scan.
• Submit suspicious files to Symantec for analysis.
