Detailsinfo

A vulnerability was found in Cisco IOS up to 12.2t (Router Operating System). It has been declared as critical. Affected by this vulnerability is an unknown function of the component ICMP Redirect Routing Table. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification).

The weakness was disclosed 02/11/2003 by Damir Rajnovic with Cisco as not defined posting (Bugtraq). It is possible to read the advisory at securityfocus.com. This vulnerability is known as CVE-2003-1398 since 10/18/2007. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK.

It is possible to download the exploit at hping.org. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 11379 (Cisco IOS ICMP Redirect Message Spoofing Remote DoS (CSCdx92043)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CISCO and relying on port 161. The commercial vulnerability scanner Qualys is able to test this issue with plugin 43101 (Cisco IOS ICMP Redirect Routing Table Modification Vulnerability).

Upgrading eliminates this vulnerability. It is possible to mitigate the problem by applying the configuration setting no ip icmp redirect. The best possible mitigation is suggested to be upgrading to the latest version. Attack attempts may be identified with Snort ID 438.

The vulnerability is also documented in the databases at X-Force (11306), Tenable (11379), SecurityFocus (BID 6823†), OSVDB (51475†) and SecurityTracker (ID 1006075†).
