MoinMoin is a wiki engine. In MoinMoin before version 1.9.11, an attacker with write permissions can upload an SVG file that contains malicious javascript. This javascript will be executed in a user's browser when the user is viewing that SVG file on the wiki. Users are strongly advised to upgrade to a patched version. MoinMoin Wiki 1.9.11 has the necessary fixes and also contains other important fixes.

The cache action in action/cache.py in MoinMoin through 1.9.10 allows directory traversal through a crafted HTTP request. An attacker who can upload attachments to the wiki can use this to achieve remote code execution.

Cross-site scripting (XSS) vulnerability in the link dialogue in GUI editor in MoinMoin before 1.9.10 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the link dialogue in GUI editor in MoinMoin before 1.9.8 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

MoinMoin 1.9.8 allows remote attackers to conduct "JavaScript injection" attacks by using the "page creation" approach, related to a "Cross Site Scripting (XSS)" issue affecting the action=AttachFile (via page name) component.

MoinMoin 1.9.8 allows remote attackers to conduct "JavaScript injection" attacks by using the "page creation or crafted URL" approach, related to a "Cross Site Scripting (XSS)" issue affecting the action=fckdialog&dialog=attachment (via page name) component.

Directory traversal vulnerability in the _do_attachment_move function in the AttachFile action (action/AttachFile.py) in MoinMoin 1.9.3 through 1.9.5 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in a file name.

Multiple unrestricted file upload vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in an unspecified directory, as exploited in the wild in July 2012.

Cross-site scripting (XSS) vulnerability in the rsslink function in theme/__init__.py in MoinMoin 1.9.5 allows remote attackers to inject arbitrary web script or HTML via the page name in a rss link.

Multiple directory traversal vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to overwrite arbitrary files via unspecified vectors. NOTE: this can be leveraged with CVE-2012-6081 to execute arbitrary code.
