Joomla Improper Input Validation Vulnerability - CVE-2006-4466
Joomla before 1.0.11 does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter39s 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.
