CVE-2024-2976Public exploitNetwork attack vector

Authenticated memory corruption via password stack overflow

Published Mar 27, 2024 · Updated Aug 21, 2024

Stack-based buffer overflow in Tenda F1203 firmware 2.0.1.6 allows remote authenticated users to corrupt memory via a crafted password. R7WebsSecurityHandler processes the password argument for /goform/execCommand without enforcing the destination stack buffer's capacity. Low-privileged web access is required, and successful exploitation can crash the service or execute code in the firmware process.
