CVE-2020-15129

CVE-2020-15129 CVSS v3 Base Score: 4.7
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

In Traefik before versions 1.7.26, 2.2.8, and 2.3.0-rc3, there exists a potential open redirect vulnerability in Traefik’s handling of the “X-Forwarded-Prefix” header. The Traefik API dashboard component doesn’t validate that the value of the header “X-Forwarded-Prefix” is a site relative path and will redirect to any header provided URI. Successful exploitation of an open redirect can be used to entice victims to disclose sensitive information. Active Exploitation of this issue is unlikely as it would require active header injection, however the Traefik team addressed this issue nonetheless to prevent abuse in e.g. cache poisoning scenarios.
