CVSS v2.0
7.5
High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
PHP version 5.2.0
Description
A buffer underflow issue exists in the filtering extension of PHP, specifically in the PHP FILTER TRIM DEFAULT macro. This allows attackers to execute arbitrary code by calling the
filter var function with certain modes, such as FILTER VALIDATE INT. The issue arises when filter writes a null byte in whitespace preceding the buffer.Recommendations
For PHP version 5.2.0, consider disabling the
filter var function with modes like FILTER VALIDATE INT until a patch is available to prevent potential code execution. Restrict access to the filtering extension to minimize the risk of exploitation.Exploit
