Summary
An unauthenticated attacker can trick a user with the "admin" or "sc_admin" role into opening a crafted Splunk Web URL. The resulting dashboard searches could run arbitrary SPL commands with the victim's permissions, potentially exposing data and affecting search results or lookup data. The vulnerability is due to improper neutralization of caller-supplied values in Splunk Secure Gateway dashboards.
Risk Assessment
An attacker could gain access to admin data or modify search results, potentially compromising data confidentiality and integrity.
Recommendation
Upgrade Splunk Enterprise to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 and Splunk Secure Gateway to version 3.10.9, 3.9.23, or 3.8.70 or later.
Original NVD description (English source)
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.
