MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" roles could submit a crafted knowledge bundle delta to delete arbitrary files accessible to Splunk Enterprise on a cluster manager. The vulnerability is possible because knowledge bundle delta processing does not restrict removal paths to the staging directory and the endpoint does not enforce the expected authorization boundary.
Risk Assessment
An attacker could delete critical system files, potentially leading to system integrity compromise and service disruption.
Recommendation
Upgrade Splunk Enterprise to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 (or later), which includes the fix.
