CVE-2025-9303
A security flaw has been discovered in TOTOLINK A720R 4.1.5cu.630_B20250509. This issue affects the function setParentalRules of the file /cgi-bin/cstecgi.cgi. Performing manipulation of the argument desc results in buffer overflow. The attack is possible to be carried out remotely. The exploit has been released to the public and may be exploited.
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: 0.85%
- Percentil entre todas las CVEs puntuadas: 57
- 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 movement75 % - Impacto principal
T1059Command and Scripting Interpreterexecution70 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation65 %
Buffer overflow en parámetro 'desc' de servicio remoto con PR:L permite RCE y escalada. AV:N, PR:L, VI:H/VC:H sustentan T1210 como explotación y T1059/T1068 como impactos.
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.
