CVE-2010-4682: Memory leak on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software before 8.2(3) all...

Security readout for executives and security teams

This flaw could let a remote party exhaust memory on Cisco ASA 5500 firewalls by repeatedly making failed LDAP authentication attempts. The business impact is denial of service: an affected security appliance may become unstable or unavailable, disrupting VPN, firewall, or access-control functions that depend on it. Exposure is most likely where Cisco ASA 5500 devices run software earlier than 8.2(3) and use LDAP-backed authentication reachable by untrusted or semi-trusted users. The provided affected-product metadata is incomplete, so asset confirmation against Cisco guidance is required. Treat this as a near-term infrastructure stability issue for any legacy ASA 5500 estate. It is not listed as KEV and has no supplied CVSS, but denial of service against a firewall or VPN appliance can create significant operational disruption. Mitigation focus: Inventory Cisco ASA 5500 appliances and record their software versions.; Prioritize devices running ASA software before 8.2(3).; Review Cisco ASA 8.2 release notes and vendor guidance for the fixed release path..
