[GLSA-200503-02] phpBB: Multiple vulnerabilities

Vulnerability Assessment Summary
phpBB: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200503-02
(phpBB: Multiple vulnerabilities)


It was discovered that phpBB contains a flaw in the session
handling code and a path disclosure bug. AnthraX101 discovered that
phpBB permits local users to read arbitrary files, if the "Enable remote
avatars" and "Enable avatar uploading" options are set (CVE-2005-0259).
He also found out that incorrect input validation in
"usercp_avatar.php" and "usercp_register.php" makes phpBB vulnerable to
directory traversal attacks, if the "Gallery avatars" setting is
enabled (CVE-2005-0258).

Impact

Remote attackers can exploit the session handling flaw to gain
phpBB administrator rights. By providing a local and a remote location
for an avatar and setting the "Upload Avatar from a URL:" field to
point to the target file, a malicious local user can read arbitrary
local files. By inserting "/../" sequences into the "avatarselect"
parameter, a remote attacker can exploit the directory traversal
vulnerability to delete arbitrary files. A flaw in the "viewtopic.php"
script can be exploited to expose the full path of PHP scripts.

Workaround

There is no known workaround at this time.
