However, this vulnerability requires user interactions to be performed. The user must read the malicious log file using a terminal application that translates the ANSI escape codes in the vulnerable terminal.
This vulnerability can be exploited by threat actors to perform malicious actions like copying the malicious file from Splunk ITSI and reading it on their local machine.
The impact of this vulnerability on Splunk ITSI can vary depending upon the permission in the vulnerable terminal application. The CVSS score for this vulnerability has been given as 8.6 ( High ).
Remediation
As per the security advisory, Splunk has requested its users to upgrade to version 4.13.3 or 4.15.3 to patch this vulnerability. However, logs prior to the upgrade might still be at risk. To mitigate this, users are recommended to
