An actual CSRF attack was possible if an attacker also managed to retrieve the session id of a reauthenticated administrator prior to targeting them. The description in this DLA does not match what has been documented in the changelog.Debian.gz of this package version. After the upload of phpbb3 3.0.12-5+deb8u4, it became evident that CVE-2019-13776 has not yet been fixed. The correct fix for CVE-2019-13776 has been identified and will be shipped in a soon-to-come follow-up security release of phpbb3.
This is a follow-up to DLA-1942-1. There was some confusion about the correct fix for CVE-2019-13776. The correct announcement for this DLA should have been: 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.
