According to its banner, the version of PHP 5.6.x running on the remote web server is prior to 5.6.9. It is, therefore, affected by multiple vulnerabilities :
Multiple unspecified flaws in pcrelib.
(CVE-2015-2325, CVE-2015-2326)
A flaw in the phar_parse_tarfile function in ext/phar/tar.c could allow a denial of service via a crafted entry in a tar archive.
(CVE-2015-4021)
Multiple flaws exist related to using pathnames containing NULL bytes. A remote attacker can exploit these flaws, by combining the ‘\0’ character with a safe file extension, to bypass access restrictions. This had been previously fixed but was reintroduced by a regression in versions 5.4+. (CVE-2006-7243, CVE-2015-4025)
An integer overflow condition exists in the ftp_genlist() function in ftp.c due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or possible remote code execution. (CVE-2015-4022)
A flaw exists in the multipart_buffer_headers() function in rfc1867.c due to improper handling of multipart/form-data in HTTP requests. A remote attacker can exploit this flaw to cause a consumption of CPU resources, resulting in a denial of service condition.
(CVE-2015-4024)
A security bypass vulnerability exists due to a flaw in the pcntl_exec implementation that truncates a pathname upon encountering the ‘\x00’ character. A remote attacker can exploit this, via a crafted first argument, to bypass intended extension restrictions and execute arbitrary files. (CVE-2015-4026)
A NULL pointer dereference flaw exists in the xsl_ext_function_php() function in xsltprocessor.c due to improper validation of user-supplied input. A remote attacker can exploit this to cause a denial of service condition.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
