SynopsisThe remote web server uses a version of PHP that is affected by multiple flaws.
DescriptionAccording to its banner, the version of PHP installed on the remote host is older than 4.4.1 or 5.0.6. Such versions fail to protect the '$GLOBALS' superglobals variable from being overwritten due to weaknesses in the file upload handling code as well as the 'extract()' and 'import_request_variables()' functions. Depending on the nature of the PHP applications on the affected host, exploitation of this issue may lead to any number of attacks, including arbitrary code execution.
In addition, these versions may enable an attacker to exploit an integer overflow flaw in certain certain versions of the PCRE library, to enable PHP's 'register_globals' setting even if explicitly disabled in the configuration, and to launch cross-site scripting attacks involving PHP's 'phpinfo()' function.
SolutionUpgrade to PHP version 4.4.1 / 5.0.6 or later.
