Detailsinfo

A vulnerability, which was classified as critical, was found in Samsung TV (affected version not known). This affects some unknown functionality of the component MAC Address Handler. 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 summary by CVE is:

The Samsung D6000 TV and possibly other products allows remote attackers to cause a denial of service (crash) via a long string in certain fields, as demonstrated by the MAC address field, possibly a buffer overflow.

The weakness was shared 04/19/2012 by Luigi Auriemma as not defined mailinglist post (Website). It is possible to read the advisory at aluigi.org. The vendor was not involved in the public release. This vulnerability is uniquely identified as CVE-2012-4330 since 08/14/2012. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Luigi Auriemma and been published immediately after the advisory. The exploit is shared for download at aluigi.org. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.

It is possible to mitigate the weakness by firewalling tcp/55000. The problem might be mitigated by replacing the product with Panasonic TV, Sony TV, ... as an alternative. The best possible mitigation is suggested to be applying a restrictive firewalling. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (74928), Exploit-DB (18751), SecurityFocus (BID 53161†), OSVDB (81222†) and SecurityTracker (ID 1026976†). The entry VDB-5258 is related to this item. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
