Overview

CVE-2008-5230 is a medium-severity vulnerability affecting cisco ios. It was published on November 25, 2008 and has a CVSS 2.0 base score of 6.8 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 6.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Temporal Key Integrity Protocol (TKIP) implementation in unspecified Cisco products and other vendors' products, as used in WPA and WPA2 on Wi-Fi networks, has insufficient countermeasures against certain crafted and replayed packets, which makes it easier for remote attackers to decrypt packets from an access point (AP) to a client and spoof packets from an AP to a client, and conduct ARP poisoning attacks or other attacks, as demonstrated by tkiptun-ng.

Remediation

Check the references section for vendor advisories and patches from cisco. Update ios to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
