CVE-2025-9482
Estado: AnalizadaAlta (7.4)—
A vulnerability was detected in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This impacts the function portRangeForwardAdd of the file /goform/portRangeForwardAdd. The manipulation of the argument ruleName/schedule/inboundFilter/TCPPorts/UDPPorts results in stack-based buffer overflow. The attack can be executed remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
- Puntuación base: 7.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 8.96%
- Percentil entre todas las CVEs puntuadas: 95
- Fecha de la puntuación: 4/10/2026
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 Interpreterexecution75 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation70 %
Stack-based buffer overflow en servicio remoto (portRangeForwardAdd) accesible con PR:L. Buffer overflow típicamente permite ejecución de código (T1059) y potencialmente escalada a root (T1068). Vector CVSS: AV:N/AC:L/PR:L/VC:H/VI:H/VA:H confirma acceso remoto con privilegios previos.
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.
