Vulnerability in htmlparse.pike in Roxen Web Server 1.3.11 and earlier, possibly related to recursive parsing and referer tags in RXML.

Roxen web server earlier than 2.0.69 allows allows remote attackers to bypass access restrictions, list directory contents, and read source code by inserting a null character (%00) to the URL.

A module in Roxen 2.0 before 2.0.92, and 2.1 before 2.1.264, does not properly decode UTF-8, Mac and ISO-2202 encoded URLs, which could allow a remote attacker to execute arbitrary commands or view arbitrary files via an encoded URL.
