WAGO: Vulnerabilities in WAGO Industrial-Managed Switches

view advisory published 2025-12-10

Two remote stack buffer overflow vulnerabilities were discovered in WAGO industrial switches. These issues originate from unsafe input handling in custom HTTP request parsing functions within the lighttpd binary. The affected binary lacks modern security features such as PIE and RELRO, increasing the risk of successful exploitation.
