Detailsinfo

A vulnerability was found in Cisco IOS XR (Router Operating System) (unknown version). It has been classified as problematic. Affected is an unknown code block of the component ICMP Handler. The manipulation of the argument timeout=0 as part of a ICMP Echo Packet 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 availability. CVE summarizes:

Cisco IOS XR allows local users to cause a denial of service (Silicon Packet Processor memory corruption, improper mutex handling, and device reload) by starting an outbound flood of large ICMP Echo Request packets and stopping this with a CTRL-C sequence, aka Bug ID CSCui60347.

The weakness was shared 08/12/2013 with Cisco as CSCui60347 as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is traded as CVE-2013-3464 since 05/06/2013. The attack needs to be approached locally. The requirement for exploitation is a authentication. Technical details and a public exploit are known.

After immediately, there has been an exploit disclosed. It is declared as proof-of-concept. As 0-day the estimated underground price was around $5k-$25k.

It is possible to mitigate the weakness by firewalling ICMP.

The vulnerability is also documented in the databases at X-Force (86385), SecurityFocus (BID 61761†) and OSVDB (96175†). Once again VulDB remains the best source for vulnerability data.
