TITLE:
TWiki "image" Directory Traversal and Command Execution

SECUNIA ADVISORY ID:
SA31849

VERIFY ADVISORY:
http://secunia.com/advisories/31849/

CRITICAL:
Less critical

IMPACT:
Exposure of system information, Exposure of sensitive information,
System access

WHERE:
>From remote

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

DESCRIPTION:
A security issue has been reported in TWiki, which can be exploited
by malicious people to disclose sensitive information or to
compromise a vulnerable system.

Input passed to the "image" parameter in bin/configure is not
properly sanitised before being used in a call to "open()". This can
be exploited to read arbitrary files from local resources via
directory traversal attacks or to execute arbitrary commands via
shell meta-characters.

Successful exploitation requires that the application is improperly
installed, allowing unrestricted access to the bin/configure script
(contrary to the documentation).

The security issue is reported in versions prior to 4.2.3.

SOLUTION:
Update to version 4.2.3.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Sven, Vicki, David, and Michael.
