Package        : phpbb3
Version        : 3.0.12-5+deb8u4
CVE ID         : 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.

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.

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

We recommend that you upgrade your phpbb3 packages.
