CVE-2026-100502
Flame through 2.4.0 contains an insufficient session expiration vulnerability in the login endpoint that allows attackers with former admin access to obtain tokens with arbitrary lifespans by supplying unvalidated duration parameters. Attackers can mint near-permanent administrator tokens that survive password changes, retaining full control of the dashboard since tokens are verified only against a static JWT secret that is never rotated.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/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: 5.9
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.29%
- Percentil entre todas las CVEs puntuadas: 20
- 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 movement65 % - Impacto principal
T1078.004Cloud Accountsstealth · persistence · privilege escalation · initial access75 % - Impacto secundario
T1098.003Additional Cloud Rolespersistence · privilege escalation70 % - Impacto secundario
T1556.004Network Device Authenticationdefense impairment · persistence · credential access60 %
Vector AV:N con PR:H (exige privilegios admin previos) y AC:H sugiere explotación de servicio remoto. Falta de validación de duración en tokens JWT permite crear credenciales persistentes que eluden rotación de secretos.
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.
