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.

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.

security/__init__.py in MoinMoin 1.9 through 1.9.4 does not properly handle group names that contain virtual group names such as "All," "Known," or "Trusted," which allows remote authenticated users with virtual group membership to be treated as a member of the group.

Multiple cross-site scripting (XSS) vulnerabilities in MoinMoin 1.9.x before 1.9.3 allow remote attackers to inject arbitrary web script or HTML via crafted content, related to (1) action/SlideShow.py, (2) action/anywikidraw.py, and (3) action/language_setup.py, a similar issue to CVE-2010-2487.

Multiple cross-site scripting (XSS) vulnerabilities in MoinMoin 1.7.3 and earlier, 1.8.x before 1.8.8, and 1.9.x before 1.9.3 allow remote attackers to inject arbitrary web script or HTML via crafted content, related to (1) Page.py, (2) PageEditor.py, (3) PageGraphicalEditor.py, (4) action/CopyPage.py, (5) action/Load.py, (6) action/RenamePage.py, (7) action/backup.py, (8) action/login.py, (9) action/newaccount.py, and (10) action/recoverpass.py.

Multiple cross-site scripting (XSS) vulnerabilities in MoinMoin 1.7.3 and earlier, and 1.9.x before 1.9.3, allow remote attackers to inject arbitrary web script or HTML via crafted content, related to (1) action/LikePages.py, (2) action/chart.py, and (3) action/userprofile.py, a similar issue to CVE-2010-2487.

Cross-site scripting (XSS) vulnerability in action/Despam.py in the Despam action module in MoinMoin 1.8.7 and 1.9.2 allows remote authenticated users to inject arbitrary web script or HTML by creating a page with a crafted URI.
