TITLE:
TWiki CGI Session File Unspecified Perl Code Execution

SECUNIA ADVISORY ID:
SA24091

VERIFY ADVISORY:
http://secunia.com/advisories/24091/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
TWiki
http://secunia.com/product/4248/

DESCRIPTION:
Andrew Moise has reported a vulnerability in TWiki, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the program loading and executing
CGI session files from a temporary directory (by default the
world-writable "/tmp"). This can be exploited by creating a specially
crafted CGI session file in the directory, which causes it to be
loaded and executed as Perl code with the privileges of the web
server under unspecified circumstances.

NOTE: It is possible to exploit this by running malicious CGI or PHP
scripts on a shared server where another customer runs TWiki.

The vulnerability is reported in 4.x versions prior to 4.1.1 and in
TWiki SessionPlugin prior to 2.992.

SOLUTION:
Update to version 4.1.1 or TWiki SessionPlugin 2.992.

PROVIDED AND/OR DISCOVERED BY:
Andrew Moise
