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 is different from CVSS.

VPR Score: 4.4

Synopsis

The remote web server is affected by a data disclosure vulnerability.

Description

According to its Server response header, the installed version of nginx is prior to 1.12.1 or 1.13.x prior to 1.13.3.
It is, therefore, affected by an integer overflow vulnerability in the range filter module. An unauthenticated, remote attacker can exploit this, via a specially crafted request to disclose potentially sensitive information.

Solution

Either apply the patch manually or upgrade to nginx 1.12.1 / 1.13.3 or later.
