Cisco Secure Firewall ASA and FTD devices are vulnerable to a denial of service attack through the Remote Access SSL VPN feature, where authenticated attackers can trigger unvalidated input processing in the Lua interpreter to force device reloads. The vulnerability stems from insufficient input validation in the Lua interpreter and can be exploited by sending specially crafted HTTP packets over an existing VPN connection. No patch is currently available for this HIGH severity issue (CVSS 7.7).
Unauthenticated remote access to restricted VPN web server endpoints in Cisco Secure ASA and Firepower Threat Defense (FTD) software exposes internal VPN-related URLs that require no credentials to reach, due to improper HTTP(S) input validation (CWE-862 - Missing Authorization). Confirmed actively exploited (CISA KEV), with a publicly available proof-of-concept and EPSS at the 97th percentile, making this a high-priority threat for any organization running remote-access VPN on ASA or FTD hardware. A related attack variant - disclosed November 5, 2025, and intersecting with CVE-2025-20333 - can additionally trigger unexpected device reloads on unpatched appliances, compounding the risk with a denial-of-service impact that brings the availability score to High.
