Detailsinfo

A vulnerability was found in Broadcom ACSD. It has been classified as critical. Affected is some unknown functionality of the component Wireless Channel Service. The manipulation of the argument acsd 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. CVE summarizes:

Buffer overflow in Broadcom ACSD allows remote attackers to execute arbitrary code via a long string to TCP port 5916. This component is used on routers of multiple vendors including ASUS RT-AC66U and TRENDnet TEW-812DRU.

The bug was discovered 07/27/2013. The weakness was published 03/14/2017 by Jacob Holcomb as EDB-ID 27133 as not defined exploit (Exploit-DB). The advisory is available at exploit-db.com. This vulnerability is traded as CVE-2013-4659 since 06/24/2013. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

A public exploit has been developed by Jacob Holcomb in Python and been published before and not just after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1326 days. During that time the estimated underground price was around $0-$5k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 43304 (ASUS RT-AC66U Multiple Buffer Overflow Vulnerabilities).

It is possible to mitigate the weakness by firewalling tcp/5916.

The vulnerability is also documented in the databases at Exploit-DB (27133) and OSVDB (95778†). If you want to get best quality of vulnerability data, you may have to visit VulDB.
