CVE-2016-15049: Nagios Log Server

Medium severity, CVSS 5.4. EPSS: 0.5% chance of exploitation in the next 30 days.

Nagios Log Server versions prior to 1.4.2 are vulnerable to cross-site scripting (XSS) in the Dashboards section when rendering log entries in the Logs table. Untrusted log content was not safely encoded for the output context, allowing attacker-controlled data present in logs to execute script in the victim’s browser within the application origin.

Affected products

• Nagios Log Server: before 1.4.2 (fixed in 1.4.2)
