CVE-2008-2108

Estado: ModificadaCrítica (9.8)—

La macro GENERATE_SEED de PHP 4.x versiones anteriores a la 4.4.8 y 5.x versiones anteriores a la 5.2.5, cuando se ejecuta en sistemas de 64 bits, realiza un producto que genera una porción de bits cero durante la conversión debido a la falta de precisión, lo que provoca 24 bits de entropía y simplifican los ataques por fuerza bruta contra mecanismos de protección que utilizan la secuencia generada y las funciones mt-rand.

CVSS

Probabilidad de explotación (EPSS)

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).
