PHP 5.4.x < 5.4.40 / 5.5.x < 5.5.24 / 5.6.x < 5.6.8 'php_sdl.c' WSDL Injection

medium Nessus Network Monitor Plugin ID 8789
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server uses a version of PHP that is affected by a SOAP WSDL injection vulnerability.


Versions of PHP 5.4.x earlier than 5.4.40, 5.5.x earlier than 5.5.24, or 5.6.x earlier than 5.6.8 contain a flaw in the cache directory that is due to the program creating files for the cache in a predictable manner. This may allow a remote attacker to inject WSDL files and have them be used in place of the intended file. Specifically, the default 'soap.wsdl_cache_dir' setting in 'php.ini-production' and 'php.ini-development' specifies the /tmp directory, which makes it easier for local users to conduct WSDL injection attacks by creating a file under /tmp with a predictable filename that is used by the 'get_sdl' function in 'ext/soap/php_sdl.c'.


Use a directory other than /tmp for the WSDL cache directory.
