Title: Festival Insecure Command Local Privilege Escalation and Remote Code Execution Vulnerability
Severity: CRITICAL
Description:
Festival is a text-to-speech accessibility application available for multiple operating platforms.
The application is prone to a privilege-escalation and code-execution vulnerability.
The application daemon runs with superuser privileges and listens on localhost port 1314 (127.0.0.1:1314), but does not require a password before executing arbitrary commands submitted via localhost.
Local attackers can exploit this issue to gain superuser privileges on computers running the affected application.
Under certain circumstances, this issue may allow remote code to run. This depends on the configuration of the affected daemon process.
This issue affects Festival 1.95 (2.0 beta) and prior versions.
