TITLE:
MediaWiki Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA38856
VERIFY ADVISORY:
http://secunia.com/advisories/38856/
DESCRIPTION:
A vulnerability and a security issue have been reported in MediaWiki,
which can be exploited by malicious users to disclose sensitive
information and bypass certain security restrictions.
1) An error exists within the CSS validation function which can be
exploited to disclose potentially sensitive information by displaying
external images in wiki pages.
Successful exploitation requires "Editor" permissions to wiki pages.
The vulnerability is reported in versions prior to 1.15.2.
2) The security issue is caused due to a missing user permissions
check within the "thumb.php" script. This can be exploited to view
restricted images in private wikis.
Success exploitation requires an image access authentication scheme
to be configured e.g. via "img_auth.php" script.
The security issue is reported in version 1.5 and later.
SOLUTION:
Update to version 1.15.2 or later.
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
