Synopsis

A wiki application on the remote web server is affected by multiple vulnerabilities.

Description

According to its version number, the MoinMoin install hosted on the remote web server is affected by multiple vulnerabilities:

- Versions 1.9.3 up to 1.9.5 are affected by a directory traversal vulnerability because the _do_attachment_move action in 'AttachFile.py' does not properly sanitize user-supplied input. This could allow an unauthenticated, remote attacker to upload and overwrite arbitrary files on the remote host. (CVE-2012-6080)

- Versions 1.9.x up to 1.9.5 are affected by a remote code execution vulnerability because the 'twikidraw.py' action fails to properly sanitize user-supplied input. A remote, unauthenticated attacker could utilize a specially crafted request using directory traversal style characters to upload a file containing arbitrary code to the remote host. An attacker could then execute the code with the privileges of the user that runs the MoinMoin process. (CVE-2012-6081)

- Version 1.9.5 is affected by a cross-site scripting (XSS) vulnerability because the application fails to properly sanitize user-supplied input in the 'page_name' parameter when creating an rss link. An attacker could leverage this issue to inject arbitrary HTML and script code into a user's browser to be executed within the security context of the affected site. (CVE-2012-6082)

- Versions < 1.9.x are not maintained by MoinMoin developers and should be considered vulnerable.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to version 1.9.6 or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB, D2 Elliot)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the MoinMoin < 1.9.6 Multiple Vulnerabilities vulnerability:

Metasploit: exploit/unix/webapp/moinmoin_twikidraw
[MoinMoin twikidraw Action Traversal File Upload]
Exploit-DB: exploits/linux/remote/26422.rb
[EDB-26422: MoinMoin - twikidraw Action Traversal Arbitrary File Upload (Metasploit)]
D2 Elliot: moinmoin_1.9.5_rce.html
[MoinMoin 1.9.5 RCE]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.
