New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisAn application installed on the remote host is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.0. It is, therefore, affected by the following vulnerabilities:
- A stack consumption condition exists in the gdImageFillToBorder function of the gd.c script within the GD Graphics Library (libgd). An unauthenticated, remote attacker can exploit this issue, via a crafted call to imagefilltoborder using a negative color value, to cause the application to stop responding.
- A denial of service (DoS) vulnerability exists in the ext/wddx/wddx.c script. An unauthenticated, remote attacker can exploit this issue, via crafted serialized data in a wddxPacket XML document, to cause the application to stop responding. (CVE-2016-9934)
- A deserialization vulnerability exists in the ext/standard/var.c script. An unauthenticated, remote attacker can exploit this, via crafted serialized data, to the application to stop responding or execute arbitrary code on the target host. (CVE-2016-9936)
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 7.1.0 or later.
