CVE-2006-4466: n/a vulnerability

CVE-2006-4466: Joomla!

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!.

Security readout for executives and security teams

This is a legacy Joomla issue affecting versions before 1.0.11. The public record says specially shaped request parameters may cause variables not to be unset correctly, allowing remote attackers an unspecified impact. The business risk depends almost entirely on whether any very old Joomla deployment remains exposed. Exposure is most likely limited to legacy Joomla installations earlier than 1.0.11, especially internet-facing sites retained for archival, intranet, or forgotten hosting purposes. Do not treat this as a modern emergency without evidence of an exposed legacy site. If Joomla before 1.0.11 is still reachable, prioritize remediation because the impact is unspecified and the software is obsolete. Mitigation focus: Inventory any Joomla deployments and confirm exact versions.; Upgrade Joomla installations older than 1.0.11 according to vendor guidance.; Review the referenced Joomla advisory for the original fix context..
