14th percentile - higher than 14% of all known CVEs

Summary

In Splunk IT Service Intelligence (ITSI) versions below 4.13.3, 4.15.3, or 4.17.1, a malicious actor can inject ANSI escape codes into log files, which can lead to the execution of malicious code in a vulnerable terminal application. The attack requires user interaction and the use of a terminal application that translates ANSI escape codes.

Risk Assessment

The risk to the organization is that users may unknowingly execute malicious code, potentially leading to system compromise, depending on permissions in the vulnerable terminal application.

Recommendation

It is recommended to update Splunk ITSI to versions 4.13.3, 4.15.3, or 4.17.1 and educate users about the risks of opening log files from untrusted sources.

Original NVD description (English source)

In Splunk IT Service Intelligence (ITSI) versions below below 4.13.3, 4.15.3, or 4.17.1, a malicious actor can inject American National Standards Institute (ANSI) escape codes into Splunk ITSI log files that, when a vulnerable terminal application reads them, can run malicious code in the vulnerable application. This attack requires a user to use a terminal application that translates ANSI escape codes to read the malicious log file locally in the vulnerable terminal. The vulnerability also requires additional user interaction to succeed. The vulnerability does not directly affect Splunk ITSI. The indirect impact on Splunk ITSI can vary significantly depending on the permissions in the vulnerable terminal application, as well as where and how the user reads the malicious log file. For example, users can copy the malicious file from Splunk ITSI and read it on their local machine.
