CVE-2025-5408

Estado: AplazadaCrítica (9.3)—

A vulnerability was found in WAVLINK QUANTUM D2G, QUANTUM D3G, WL-WN530G3A, WL-WN530HG3, WL-WN532A3 and WL-WN576K1 up to V1410_240222 and classified as critical. Affected by this issue is the function sys_login of the file /cgi-bin/login.cgi of the component HTTP POST Request Handler. The manipulation of the argument login_page leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1059 Command and Scripting Interpreterexecution85 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation75 %

Buffer overflow en handler HTTP remoto sin autenticación (AV:N, PR:N) permite ejecución de código (VC:H). Acceso a red sin privilegios → T1190. Impacto: ejecución de comandos arbitrarios (T1059) y potencial escalada de privilegios en dispositivo de red (T1068).
