CVE-2006-3207: Ultimate PHP Board

Medium severity, CVSS 5.0. EPSS: 1.3% chance of exploitation in the next 30 days.

Directory traversal vulnerability in newpost.php in Ultimate PHP Board (UPB) 1.9.6 and earlier allows remote attackers to overwrite arbitrary files via a .. (dot dot) sequence and trailing null (%00) byte in the id parameter, as demonstrated by injecting a Perl CGI script using "[NR]" sequences in the message parameter, then calling close.php with modified id and t_id parameters to chmod the script. NOTE: this issue might be resultant from dynamic variable evaluation.
