CVE-2010-2818: Unspecified vulnerability in the SunRPC inspection feature on the Cisco Firewall Services Module (FWSM) wit...

Security readout for executives and security teams

This flaw can let a remote attacker crash and reload affected Cisco FWSM firewall modules by sending crafted SunRPC traffic. The main business risk is firewall disruption and service interruption, not data theft. Evidence provided does not show active exploitation. Exposure is likely limited to organizations still operating Cisco FWSM on Catalyst 6500 switches or 7600 routers with affected software trains. Modern environments that retired FWSM are unlikely exposed. Treat as a legacy infrastructure availability risk. Prioritize remediation where FWSM protects important network segments, especially if internet-adjacent or handling untrusted traffic. Mitigation focus: Upgrade affected Cisco FWSM software to the fixed version for its release train or later.; Review Cisco’s advisory for supported upgrade paths and any operational caveats.; Prioritize replacement if FWSM hardware or software is unsupported..
