VERIFY ADVISORY:
http://secunia.com/advisories/23826/
CRITICAL:
Moderately critical
IMPACT:
Security Bypass, System access
WHERE:
>From remote
SOFTWARE:
Django 0.x
http://secunia.com/product/13287/
DESCRIPTION:
Some vulnerabilities have been reported in Django, which can be
exploited by malicious users to bypass certain security restrictions
or malicious people to compromise a vulnerable system.
1) The bin/compile-messages.py script does not correctly escape the
filename of .po message files. This can be exploited to execute
arbitrary shell commands via a maliciously named .po file.
2) The authentication middleware incorrectly caches the
"request.user" parameter between requests, which could be exploited
to e.g. access pages as another user.
The vulnerabilities are reported in version 0.95. Other versions may
also be affected.
SOLUTION:
Fixed in the SVN repository.
