CVE-2025-8826
Estado: AnalizadaAlta (7.4)—
A vulnerability has been found in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. This vulnerability affects the function um_rp_autochannel of the file /goform/RP_setBasicAuto. The manipulation of the argument apcli_AuthMode_2G/apcli_AuthMode_5G leads to stack-based buffer overflow. The attack can be initiated 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.

- Puntuación base: 7.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.00%
- Percentil entre todas las CVEs puntuadas: 62
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1210Exploitation of Remote Serviceslateral movement85 % - Impacto principal
T1059Command and Scripting Interpreterexecution80 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation75 %
Vector CVSS de red con PR:L (red, privilegios bajos) lleva a T1210. Stack overflow permite ejecutar código (T1059) y potencialmente escalar privilegios (T1068) en dispositivo remoto.
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
