Secunia Research has discovered a weakness and multiple vulnerabilities in Support Incident Tracker, which can be exploited by malicious users to disclose sensitive information, conduct SQL injection attacks, and compromise a vulnerable system and by malicious people to conduct cross-site scripting attacks.
1) An error in ftp_upload_file.php does not properly verify uploaded file names and can be exploited to disclose the attachments directory name.
2) Input passed via the "search_string" parameter to search.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Input passed via uploaded file names to incident_attachments.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation of this vulnerability requires that "magic_quotes_gpc" is disabled.
4) Input passed via e.g. the "application_name" parameter to config.php (when "action" is set to "save") is not properly sanitised before being used in an "eval()" call. This can be exploited to execute arbitrary PHP code.
Successful exploitation of this vulnerability requires the "Administrate" permission.
5) An error in the ftp_upload_file.php script does not properly validate uploaded files and can be exploited to execute arbitrary PHP code by uploading a PHP file.
NOTE: This vulnerability can be exploited in combination with vulnerability #1.
The weakness and the vulnerabilities are confirmed in version 3.65. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised and verified.
