#VU110344 Input validation error in PHP - CVE-2008-2107
Vulnerability identifier: #VU110344
Vulnerability risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID:
CWE-ID:
CWE-20
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
PHP
Universal components / Libraries /
Scripting languages
Vendor: PHP Group
Description
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 32-bit systems, performs a multiplication using values that can produce a zero seed in rare circumstances, which allows context-dependent attackers to predict subsequent values of the rand and mt_rand functions and possibly bypass protection mechanisms that rely on an unknown initial seed.
Mitigation
Install update from vendor's website.
Vulnerable software versions
PHP: 5, 5.0.0, 5.0.1, 5.0.2, 5.0.3, 5.0.4, 5.0.5, 5.1.0, 5.1.1, 5.1.2, 5.1.3, 5.1.4, 5.1.5, 5.1.6, 5.2, 5.2.1, 5.2.2, 5.2.3, 5.2.4
