CVE-2024-8175Network attack vector

Web server crash via unchecked TLS error

Published Sep 25, 2024 · Updated Sep 25, 2024

Improper error handling in CODESYS Control web servers allows remote attackers to crash the web server task with crafted TLS packets. The optional CmpWebServer component fails to correctly check an underlying function return value for unusual TLS input, then accesses invalid memory. Exploitation requires an unauthenticated HTTPS connection to an enabled CODESYS WebVisu web server and interrupts only the web server task.
