| Detailed Description |
The remote host is running a version of PHP that is affected by an arbitrary code execution vulnerability.
Specifically, the fix for the hash collision denial of service vulnerability (CVE-2011-4885) introduces a remote code execution vulnerability in the function 'php_register_variable_ex()' in the file 'php_variables.c'. A new configuration variable, 'max_input_vars', was added as a part of the fix. If the number of input variables exceeds this value and the variable being processed is an array, code execution can occur.
* Note: This check solely relied on the version number of the remote WebLogic server to assess this vulnerability, so this might be a false positive.
