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: 5.9
Synopsis
The version of PHP running on the remote web server is affected by a heap-based buffer overflow vulnerability.
Description
According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.9. It is, therefore, affected by a heap-based buffer overflow condition exists in the ext/standard/var_unserializer.re script due to improper use of the hash API for key deletion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to PHP version 7.1.9 or later.
