Summary

In Splunk SOAR (Security Orchestration, Automation, and Response) versions below 8.5.0, an unauthenticated attacker could inject American National Standards Institute (ANSI) escape codes into SOAR application log files through specially crafted HTTP request paths, which a terminal emulator might interpret when an administrator views the logs.<br><br>The injection is possible because SOAR does not strip control characters from HTTP request paths before writing them to application logs.
