CVE-2010-1580: Unspecified vulnerability in the SunRPC inspection feature on Cisco Adaptive Security Appliances (ASA) 5500...

Security readout for executives and security teams

This is a denial-of-service flaw in Cisco firewall appliances. A remote attacker could send crafted SunRPC UDP traffic that causes an affected ASA or PIX device to reload, interrupting network connectivity protected by that device. Exposure is most relevant for organizations still running Cisco ASA 5500 or PIX 500 devices on the affected legacy software trains, especially where SunRPC UDP traffic reaches inspection paths. Treat this as high priority if legacy Cisco firewalls still protect critical traffic. The impact is availability, not data theft, but firewall reloads can cause outages across dependent services. Mitigation focus: Upgrade affected ASA software to the fixed versions listed in the CVE description or later.; Check Cisco's advisory for product-specific remediation and operational caveats.; Reduce exposure of SunRPC UDP traffic to affected inspection paths where feasible..
