Authenticated service interruption via inefficient regular expression
Published Jan 30, 2025 · Updated Feb 12, 2025
ReDoS in Splunk Supporting Add-on for Active Directory before 3.1.1 allows remote authenticated users to interrupt service. The add-on evaluates a vulnerable regular expression that can consume excessive CPU on crafted input; Splunk has not disclosed the command, field, or pattern involved. A low-privilege Splunk account and network access to the search head are required; the reported consequence is availability loss without data exposure or modification.
