30 December 2012
MoinMoin could be made to run programs and overwrite files.
Releases
Packages
- moin - Collaborative hypertext environment
Details
It was discovered that MoinMoin did not properly sanitize its input when
processing AnyWikiDraw and TWikiDraw actions. A remote attacker with write
access could exploit this to overwrite arbitrary files and execute
arbitrary code with the priviliges of the web server (user 'www-data').
It was discovered that MoinMoin also did not properly sanitize its input
when processing the AttachFile action. A remote attacker could exploit
this to overwrite files via directory traversal.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04
In general, a standard system update will make all the necessary changes.
