CVE-2025-60694Public exploitNetwork attack vector

Unauthenticated service interruption via unchecked CGI concatenation

Published Nov 13, 2025 · Updated Jul 5, 2026

Stack buffer overflow in Linksys E1200 v2 firmware 2.0.11.001 allows remote attackers to interrupt service via crafted HTTP requests. The validate_static_route function concatenates four user-controlled values from each route-address, netmask, and gateway CGI group into separate 20-byte buffers without length checks. No authentication or user interaction is required; CISA's assessment bounds the scored impact to service availability despite the source's code-execution claim.
