Debian DLA-1942-2 : phpbb3 regression update

high Nessus Plugin ID 129477

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2019-16993

In phpBB, includes/acp/acp_bbcodes.php had improper verification of a CSRF token on the BBCode page in the Administration Control Panel. An actual CSRF attack was possible if an attacker also managed to retrieve the session id of a reauthenticated administrator prior to targeting them.

CVE-2019-13776

phpBB allowed the stealing of an Administration Control Panel session id by leveraging CSRF in the Remote Avatar feature. The CSRF Token Hijacking lead to stored XSS.

For Debian 8 'Jessie', these problems have been fixed in version 3.0.12-5+deb8u4.

We recommend that you upgrade your phpbb3 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected phpbb3, and phpbb3-l10n packages.
