Description

Validate-Before-Canonicalize vulnerability in the checkURI function in functions.inc.php in PHPX 3.0 through 3.2.6 allows remote attackers to conduct cross-site scripting (XSS) attacks via hex-encoded tags, which bypass the check for literal "<", ">", "(", and ")" characters, as demonstrated using the limit parameter to forums.php and a variety of other vectors.
