This flaw impacts Splunk Enterprise versions below 10.4.1, 10.2.5, 10.0.8, and 9.4.13, and Splunk Cloud Platform versions below 10.5.2605.0, 10.4.2604.7, 10.3.2512.16, 10.2.2510.18, and 10.1.2507.24. An attacker can exploit this vulnerability by crafting a malicious GET request that, when accessed by a Splunk user holding the \u003ccode\u003elist_deployment_server\u003c/code\u003e capability, will execute arbitrary Search Processing Language (SPL) searches on the user's behalf. Crucially, these malicious SPL searches run with the privileges of the \u003ccode\u003esplunk-system-user\u003c/code\u003e, bypassing security controls and enabling access to sensitive assets like stored credentials and indexed data. The vulnerability stems from the Deployment Server endpoints in Splunk Web failing to validate CSRF tokens on GET requests and not correctly neutralizing caller-supplied input before it is incorporated into an SPL search.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eCraft Malicious Link:\u003c/strong\u003e The attacker crafts a malicious Uniform Resource Locator (URL) containing a specially crafted GET request targeting a vulnerable Splunk Deployment Server endpoint.

The compromise of indexed data can expose sensitive corporate information, personal identifiable information (PII), and other confidential records, leading to significant data breaches, compliance violations, and operational disruption.
