Official Description
bb_smilies.php and bbcode_ref.php in PHP-Nuke 4.4 allows remote attackers to read arbitrary files and gain PHP administrator privileges by inserting a null character and .. (dot dot) sequences into a malformed username argument.
Technical Analysis
CVE-2001-0320 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
