CVE-2010-2820: Unspecified vulnerability in the SunRPC inspection feature on the Cisco Firewall Services Module (FWSM) wit...

Security readout for executives and security teams

This flaw could let a remote attacker crash and reload a Cisco Firewall Services Module by sending crafted SunRPC traffic. The business risk is network disruption, especially where legacy Catalyst 6500 or 7600 platforms still protect important segments. Exposure is likely limited to organizations still operating Cisco FWSM on Catalyst 6500 series switches or 7600 series routers with the affected software trains and SunRPC inspection enabled. Treat as urgent if legacy FWSM still sits in critical network paths. The impact is service interruption, not data theft in the provided sources, but a firewall reload can still create major outage risk. Mitigation focus: Inventory Cisco FWSM deployments on Catalyst 6500 and 7600 platforms.; Upgrade affected FWSM trains to Cisco fixed versions or later.; Prioritize internet-facing or untrusted-zone inspection paths first..
