In Splunk Enterprise versions below 10.2.0, 10.0.4, 9.4.9, and 9.3.10, and Splunk Cloud Platform versions below 10.2.2510.5, 10.0.2503.12, 10.1.2507.16, and 9.3.2411.124, a user who holds a role that contains the high-privilege capability edit_cmd could execute arbitrary shell commands using the unarchive_cmd parameter for the /splunkd/__upload/indexing/preview REST endpoint.
AnalysisAI
Arbitrary shell command execution in Splunk Enterprise and Cloud Platform allows authenticated users with the edit_cmd capability to inject commands through the unarchive_cmd parameter in the preview upload endpoint. Affected versions include Splunk Enterprise below 10.2.0, 10.0.4, 9.4.9, and 9.3.10, as well as corresponding Cloud Platform versions. An attacker with high-privilege roles could achieve remote code execution on vulnerable systems, though no patch is currently available.
Technical ContextAI
Classified as CWE-77 (Command Injection). In Splunk Enterprise versions below 10.2.0, 10.0.4, 9.4.9, and 9.3.10, and Splunk Cloud Platform versions below 10.2.2510.5, 10.0.2503.12, 10.1.2507.16, and 9.3.2411.124, a user who holds a role that contains the high-privilege capability edit_cmd could execute arbitrary shell commands using the unarchive_cmd parameter for the /splunkd/__upload/indexing/preview REST endpoint.
