Nagios Log Server 2
| CVE | Vulnerability Summary | Remediation Summary |
|---|---|---|
| CVE-2019-15898 | A reflected (XSS) vulnerability has been discovered in Nagios Log Server via the username on the Login page. | Update to Nagios Log Server 2.0.8 and above |
Nagios Core 4
| CVE | Vulnerability Summary | Remediation Summary |
|---|---|---|
| CVE-2018-18245 | A cross-site scripting (XSS) vulnerability has been discovered 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. |
Update to Nagios Core 4.4.3 or Nagios XI 5.5.9 and above (You can also patch this with Core maint branch) |
