Detailsinfo

A vulnerability classified as critical was found in Cisco IOS up to 15.3 (Router Operating System). This vulnerability affects an unknown functionality of the component Software Protocol Translation Feature. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. CVE summarizes:

The Protocol Translation (PT) functionality in Cisco IOS 12.3 through 12.4 and 15.0 through 15.3, when one-step port-23 translation or a Telnet-to-PAD ruleset is configured, does not properly validate TCP connection information, which allows remote attackers to cause a denial of service (device reload) via an attempted connection to a PT resource, aka Bug ID CSCtz35999.

The weakness was presented 03/27/2013 as File 120984/Cis as confirmed advisory (Packetstorm). The advisory is shared for download at packetstormsecurity.com. The public release was coordinated in cooperation with the vendor. This vulnerability was named CVE-2013-1147 since 01/11/2013. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a private exploit is available.

It is declared as proof-of-concept.
