## Description

Directory traversal vulnerability in bb_lib/abbc.css.php in Unclassified NewsBoard (UNB) 1.5.3-d and possibly earlier versions, when register_globals is enabled, allows remote attackers to include arbitrary files via .. (dot dot) sequences and a trailing null byte (%00) in the design_path parameter. NOTE: this is closely related, but a different vulnerability than the ABBC[Config][smileset] parameter.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
