Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

In Splunk Enterprise versions before 8.1.2, the uri path to load a relative resource within a web page is vulnerable to path traversal. It allows an attacker to potentially inject arbitrary content into the web page (e.g., HTML Injection, XSS) or bypass SPL safeguards for risky commands. The attack is browser-based. An attacker cannot exploit the attack at will and requires the attacker to initiate a request within the victim's browser (e.g., phishing).
