Joomla! before 1.0.11 does not limit access to the Admin Popups functionality, which has unknown impact and attack vectors.
Multiple unspecified vulnerabilities in Joomla! before 1.0.11, related to "Injection Flaws," allow attackers to have an unknown impact via (1) globals.php, which uses includeonce() instead of require(); (2) the $options variable; (3) Admin Upload Image; (4) ->load(); (5) content submissions when frontpage is selected; (6) the mosPageNav constructor; (7) saveOrder functions; (8) the absence of "exploit blocking rules" in htaccess; and (9) the ACL.
comcategories in Joomla! before 1.0.12 does not validate input, which has unknown impact and remote attack vectors.

Multiple unspecified vulnerabilities in Joomla! before 1.0.12 have unknown impact and attack vectors related to (1) "unneeded legacy functions" and (2) "Several low level security fixes."
Unspecified vulnerability in comcontent in Joomla! before 1.0.11, when $mosConfighideEmail is set, allows attackers to perform the emailform and emailsend tasks.
Joomla! before 1.0.11 does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to have an unspecified impact. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Joomla!.
Directory traversal vulnerability in attachmentlibrary.php in the XStandard component for Joomla! 1.5.8 and earlier allows remote attackers to list arbitrary directories via a .. (dot dot) in the XCMSLIBRARYPATH HTTP header.
Cross-site scripting (XSS) vulnerability in Joomla! before 1.0.12 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, possibly related to poll.php or the module title.
Multiple cross-site scripting (XSS) vulnerabilities in Joomla! 1.5.7 and earlier allow remote authenticated users with certain privileges to inject arbitrary web script or HTML via (1) the title and description parameters to the comweblinks module and (2) unspecified vectors in the comcontent module related to "article submission."
