Description:
Some vulnerabilities have been reported in MoinMoin, which can be exploited by malicious people to conduct cross-site scripting attacks, bypass security restrictions, manipulate certain data, or potentially compromise a vulnerable system.
1) Input passed to the "name" parameter when logging in is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is reported in versions prior to 1.6.1.
2) Input passed to action/AttachFile.py, to PageEditor.py when renaming or deleting a page, and to the gui editor (formatter/text_gedit.py), is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
3) Input passed to the MOIN_ID cookie parameter is not properly sanitised before being used. This can be exploited to overwrite arbitrary files via directory traversal attacks.
Successful exploitation may allow to inject and execute arbitrary PHP code but depends on certain file permissions and settings of the server.
4) An error within the enforcing of ACLs in wikimacro.py can be exploited to read restricted pages.
Vulnerabilities 2#, #3, and #4 are reported in version 1.5.8. Other versions may also be affected.
Solution:
Update to version 1.6.1.
