Summary
generated automatically from NVD dataThe Twig webmail system fails to properly initialize the "vhosts" variable when it is not configured on a site. A remote attacker can supply an alternate vhosts value as an argument to index.php3, which lets them inject and run arbitrary PHP (PHP3) code. NVD lists the affected product as Twig from the Twig development team, with 2.5.1 given as a bound, and rates the flaw 7.5 (HIGH, CVSS v2.0).
