CVE-2008-2108

9.8
CRITICAL · CVSS 3.1 · EPSS 4.3% (pctl 91)

In your normal cycle

Critical by CVSS (9.8), but no sign of active exploitation.

Description

The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions.
