Description:
Secunia Research has discovered some vulnerabilities in ATutor, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, and compromise a vulnerable system.
1) Input passed to the "addslashes", "asc", and "desc" parameters in "include/html/forum.inc.php" isn't properly verified, before it is used to create a function call. This can be exploited to call an arbitrary PHP function with an arbitrary parameter (e.g. execute arbitrary shell commands with the "exec" function).
Examples:
http://[host]/include/html/forum.inc.php?addslashes=[function]&asc=[parameter]
http://[host]/include/html/forum.inc.php?addslashes=[function]&desc=[parameter]
Successful exploitation requires that "register_globals" is enabled.
2) Input passed to the "section" parameter in "body_header.inc.php" and "print.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Examples:
http://[host]/documentation/common/body_header.inc.php?section=[file]%00
http://[host]/documentation/common/print.php?section=[file]%00
Successful exploitation requires that "register_globals" is enabled and that "magic_quotes_gpc" is disabled.
3) Input passed to the "_base_href" parameter in "admin/translate.php", the "_base_path" parameter in "include/html/editor_tabs/news.inc.php", and the "p" parameter in "documentation/add_note.php" isn't 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.
The vulnerabilities have been confirmed in version 1.5.1-pl1. Other versions may also be affected.
Solution:
Apply patch.

The fixes will also be included in the upcoming 1.5.2 version.
