It is recommended that administrators running phpbb3 check for an updated version of the software for their operating system. Revision History: October 8 2019: Updated to DLA 1942-2 October 1 2019: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Package : phpbb3 Version : 3.0.12-5+deb8u4 CVE ID : CVE-2019-13776 CVE-2019-16993 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. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
