5.0
Medium
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
PHP versions prior to 5.3.9
Description
The issue arises due to insufficient input validation in the PHP language interpreter. This can be exploited by a remote attacker to cause a denial of service, specifically by consuming CPU resources. The exploitation involves sending many crafted parameters to trigger hash collisions predictably.
Recommendations
For PHP versions prior to 5.3.9, update to version 5.3.9 or later to resolve the issue. As a temporary workaround, consider restricting the ability to send many crafted parameters to PHP applications to minimize the risk of exploitation.
