CVE-2021-39211
Estado: ModificadaMedia (5.3)—💥 Exploit
GLPI is a free Asset and IT management software package. Starting in version 9.2 and prior to version 9.5.6, the telemetry endpoint discloses GLPI and server information. This issue is fixed in version 9.5.6. As a workaround, remove the file `ajax/telemetry.php`, which is not needed for usual functions of GLPI.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- Puntuación base: 5.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 4.70%
- Percentil entre todas las CVEs puntuadas: 92
- Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
