MoinMoin 1.6.2 and 1.7 does not properly enforce ACL checks when aclhierarchic is set to True, which might allow remote attackers to bypass intended access restrictions, a different vulnerability than CVE-2008-1937.
The passwordchecker function in config/multiconfig.py in MoinMoin prior to version 1.6.1 uses the cracklib and python-crack features even though they are not thread-safe, which allows remote attackers to cause a denial of service (segmentation fault and crash) via unknown vectors.
The rst parser (parser/textrst.py) in MoinMoin 1.6.1 does not check the ACL of an included page, which allows attackers to read unauthorized include files via unknown 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 before 1.8.7 and 1.9.x before 1.9.2 does not properly sanitize user profiles, which has unspecified impact and attack vectors.

As mentioned in [7]: "<ThomasWaldmann> 2) it's not just a single patch, it is quite much, you don't want to apply them manually. if you need it now, do a repo checkout and you'll have 1.9.2pre kind of"
The default configuration of cfg.packagepagesactionsexcluded in MoinMoin before 1.8.7 does not prevent unsafe package actions, which has unspecified impact and attack vectors.
MoinMoin 1.9 before 1.9.1 does not perform the expected clearing of the sys.argv array in situations where the GATEWAYINTERFACE environment variable is set, which allows remote attackers to obtain sensitive information via unspecified vectors.
MoinMoin 1.7.x before 1.7.3 and 1.8.x before 1.8.3 checks parent ACLs in certain inappropriate circumstances during processing of hierarchical ACLs, which allows remote attackers to bypass intended access restrictions by requesting an item, a different vulnerability than CVE-2008-6603.
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.
MoinMoin 1.7.1 allows remote attackers to bypass the textcha protection mechanism by modifying the textcha-question and textcha-answer fields to have empty values.
Impact 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.
Patches 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.
Workarounds It is not advised to work around this, but to upgrade MoinMoin to a patched version.
That said, a work around via a Content Security Policy in the web server might be possible.
Also, it is of course helpful if you give write permissions (which include uploading attachments) only to trusted users.

Impact The cache action in action/cache.py 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.
Patches 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.
Workarounds It is not advised to work around this, but to upgrade MoinMoin to a patched version.
That said, a work around via disabling the cache or the AttachFile action might be possible.
Also, it is of course helpful if you give write permissions (which include uploading attachments) only to trusted users.

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.
Multiple cross-site scripting (XSS) vulnerabilities in action/AttachFile.py in MoinMoin 1.8.2 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) an AttachFile sub-action in the errormsg function or (2) multiple vectors related to package file errors in the uploadform function, different vectors than CVE-2009-0260.
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.
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.
Cross-site scripting (XSS) vulnerability in the reStructuredText (rst) parser in parser/textrst.py in MoinMoin before 1.9.3, when docutils is installed or when "format rst" is set, allows remote attackers to inject arbitrary web script or HTML via a javascript: URL in the refuri attribute. NOTE: some of these details are obtained from third party information.
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.
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.
Cross-site scripting (XSS) vulnerability in the rsslink function in theme/init.py in MoinMoin before 1.9.6 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.
Directory traversal vulnerability in the doattachmentmove 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 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.
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.
