According to its banner, the version of PHP 5.4.x installed on the remote host is prior to 5.4.37. It is, therefore, affected by multiple vulnerabilities:
The CGI component has an out-of-bounds read flaw in file ‘cgi_main.c’ when nmap is used to process an invalid file that begins with a hash character (#) but lacks a newline character. A remote attacker, using a specially crafted PHP file, can exploit this vulnerability to disclose memory contents, cause a denial of service, or possibly execute code. (CVE-2014-9427)
A use-after-free memory error exists in the function ‘process_nested_data’ within ‘var_unserializer.re’ due to the improper handling of duplicate numerical keys within the serialized properties of an object. A remote attacker, using a crafted unserialize method call, can exploit this vulnerability to execute arbitrary code.
(CVE-2015-0231)
A flaw exists in function ‘exif_process_unicode’ within ‘exif.c’ that allows freeing an uninitialized pointer. A remote attacker, using specially crafted EXIF data in a JPEG image, can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-0232)
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application’s self-reported version number.
