|
|
A security audit of the MediaWiki project discovered that
|
|
MediaWiki is vulnerable to several cross-site scripting and cross-site
|
|
request forgery attacks, and that the image deletion code does not
|
|
sufficiently sanitize input parameters.

<impact type="low">
|
|
<p>
|
|
By tricking a user to load a carefully crafted URL, a remote
|
|
attacker could hijack sessions and authentication cookies to inject
|
|
malicious script code that will be executed in a user's browser session
|
|
in context of the vulnerable site, or use JavaScript submitted forms to
|
|
perform restricted actions. Using the image deletion flaw, it is also
|
|
possible for authenticated administrators to delete arbitrary files via
|
|
directory traversal.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<resolution>

<p>
|
|
All MediaWiki users should upgrade to the latest available
|
|
version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apps/mediawiki-1.3.11"</code>
