CVE-2024-11236:
PHP vulnerability analysis and mitigation
Overview
CVE-2024-11236 affects PHP versions 8.1. before 8.1.31, 8.2. before 8.2.26, and 8.3.* before 8.3.14. The vulnerability involves uncontrolled long string inputs to the ldap_escape() function on 32-bit systems, which can cause an integer overflow resulting in an out-of-bounds write (NVD).
Technical details
The vulnerability occurs in the firebird and dblib quoters where integer overflow can happen during string length calculations. The affected code in both drivers performs calculations for quoted string lengths that can potentially overflow on 32-bit systems, leading to out-of-bounds write conditions. The issue has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (PHP Advisory).
Impact
The vulnerability can potentially allow attackers to execute arbitrary code on affected systems through out-of-bounds write operations. This poses a significant security risk as it could lead to complete system compromise on vulnerable installations (Security Online).
Mitigation and workarounds
Users are strongly advised to update their PHP installations to the patched versions: 8.1.31, 8.2.26, or 8.3.14, which contain fixes for this vulnerability (NVD).
