Technical Analysis
In Splunk AI Toolkit versions 6.0 and 6.0.0, the "power" Splunk role is granted permission to modify app-provided scheduled searches. These scheduled searches run with the permissions of the search owner. An attacker with the "power" role can alter these searches to execute arbitrary SPL commands, potentially accessing all data available to the search owner and impacting system integrity. The vulnerability arises from improper permission specification for a security-critical resource.
Potential Impact
An attacker with the "power" role can execute arbitrary SPL queries with the permissions of the search owner by modifying scheduled searches. This can lead to unauthorized data access and compromise the integrity of the system. The vulnerability does not affect availability but has high confidentiality and integrity impacts.
Mitigation Recommendations
A fix is available in Splunk AI Toolkit version 6.0.1. Users should upgrade to version 6.0.1 or later to remediate this vulnerability.
