Title
SPL Injection through Splunk Web in Splunk Secure Gateway
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, an unauthenticated user could trick a user who holds the "admin" or "sc_admin" Splunk roles into opening a crafted Splunk Web Uniform Resource Locator (URL). The resulting dashboard searches could run arbitrary Search Processing Language (SPL) commands with the permissions available to the affected user. The commands could expose all relevant data available to that user and affect search results or lookup data. The vulnerability is possible because Splunk Secure Gateway dashboards do not correctly neutralize caller-supplied values before using them in dashboard searches. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
