CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/Au:N/C:C/I:C/A:C

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
nagios3 on Debian Linux

Recommendations:
For Debian 8 'Jessie', these problems have been fixed in version 3.5.1.dfsg-2+deb8u1. We recommend that you upgrade your nagios3 Linux Distribution Packages.

Summary:
Several issues were corrected in nagios3, a monitoring and management system for hosts, services and networks. CVE-2018-18245 Maximilian Boehner of usd AG found a cross-site scripting (XSS) vulnerability in Nagios Core. This vulnerability allows attackers to place malicious JavaScript code into the web frontend through manipulation of plugin output. In order to do this the attacker needs to be able to manipulate the output returned by nagios checks, e.g. by replacing a plugin on one of the monitored endpoints. Execution of the payload then requires that an authenticated user creates an alert summary report which contains the corresponding output. CVE-2016-9566 It was discovered that local users with access to an account in the nagios group are able to gain root privileges via a symlink attack on the debug log file. CVE-2014-1878 An issue was corrected that allowed remote attackers to cause a stack-based buffer overflow and subsequently a denial of service (segmentation fault) via a long message to cmd.cgi. CVE-2013-7205, CVE-2013-7108 A flaw was corrected in Nagios that could be exploited to cause a denial-of-service. This vulnerability is induced due to an off-by-one error within the process_cgivars() function, which can be exploited to cause an out-of-bounds read by sending a specially-crafted key value to the Nagios web UI.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
