CVE-2017-9538: SolarWinds Network Performance Monitor

Medium severity, CVSS 4.9. EPSS: 2.4% chance of exploitation in the next 30 days.

The 'Upload logo from external path' function of SolarWinds Network Performance Monitor version 12.0.15300.90 allows remote attackers to cause a denial of service (permanent display of a "Cannot exit above the top directory" error message throughout the entire web application) via a ".." in the path field. In other words, the denial of service is caused by an incorrect implementation of a directory-traversal protection mechanism.

Affected products

• SolarWinds Network Performance Monitor: up to and including 12.0.15300.90
