Debian LTS Advisory ([SECURITY] [DLA 1942-1] phpbb3 security update)

The remote host is missing an update for the 'phpbb3' package(s) announced via the DSA-1942-1 advisory.

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. 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.

'phpbb3' package(s) on Debian Linux.

Checks if a vulnerable package version is present on the target host.

For Debian 8 'Jessie', these problems have been fixed in version 3.0.12-5+deb8u4. We recommend that you upgrade your phpbb3 packages.
