CVE-2022-26889Network attack vector

Content injection via unsanitized relative URI path

Published May 6, 2022 · Updated Aug 3, 2024

Path traversal in Splunk Web in Splunk Enterprise before 8.1.2 allows remote attackers to inject content through a crafted relative URI. The search parameter handler fails to sanitize the URI path used to load a relative resource, enabling HTML or script injection and bypasses of risky-command safeguards. Exploitation requires Splunk Web to be enabled and a victim to initiate the crafted request in a browser, such as by following a phishing link.
