CVE-2024-7213Network attack vector

Authenticated memory corruption via oversized SSID

Published Jul 30, 2024 · Updated Aug 1, 2024

Buffer overflow in TOTOLINK A7000R 9.1.0u.6268_B20220504 allows remote authenticated users to corrupt memory through a crafted SSID. The setWizardCfg handler in /cgi-bin/cstecgi.cgi copies the attacker-controlled ssid value without verifying that it fits the destination buffer. A low-privilege management session is required, and exploitation can compromise data, alter execution, or interrupt the CGI service.
