SynopsisThe remote web server uses a version of PHP that is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.30. It is, therefore, affected by the following vulnerabilities :
- A NULL pointer dereference flaw exists in the phar_get_fp_offset() function in ext/phar/util.c that is triggered when pointing to a non-existent file. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2015-7803)
- An uninitialized pointer flaw exists in the phar_make_dirstream() function in ext/phar/dirstream.c that is triggered when handling a zip entry filename that consists of a single forward slash. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or to disclose sensitive information. (CVE-2015-7804)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to PHP version 5.5.30 or later.
