A vulnerability classified as critical has been found in Kerio Unified Threat Management 9.1.0. Affected is an unknown part. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability.

The bug was discovered 08/24/2016. The weakness was released 09/22/2016 by R. Freingruber and R. Tavakoli with SEC Consult as 20160922-0 as not defined mailinglist post (Full-Disclosure). The advisory is shared for download at seclists.org. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The advisory points out:

One of the PHP scripts allows the allocation of memory inside the main binary (winroute) of Kerio Control. Winroute contains the code of most services (e.g. the webserver, PHP, network related functionality, ...). The memory will not be freed after finishing the request and can therefore be used to spray payloads to the whole memory space.

The vulnerability was handled as a non-public zero-day exploit for at least 29 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 9.1.3 eliminates this vulnerability.
