CVE-2016-9847
Estado: ModificadaMedia (5.3)—
Se descubrió un problema en phpMyAdmin. Cuando el usuario no especifica una clave blowfish_secret para cifrar las cookies, phpMyAdmin genera una en tiempo de ejecución. Se informó de una vulnerabilidad donde la forma en que se crea este valor utiliza un algoritmo débil. Esto podría permitir a un atacante determinar los usuarios blowfish_secret y potencialmente descifrar sus cookies. Todas las versiones 4.6.x (anteriores a 4.6.5), versiones 4.4.x (anteriores a 4.4.15.9) y versiones 4.0.x (anteriores a 4.0.10.18) están afectadas.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/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: 2.00%
- Percentil entre todas las CVEs puntuadas: 80
- Fecha de la puntuación: 8/10/2026
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).
