What is CVE-2025-34099?

An unauthenticated command injection vulnerability is present in selected versions of VICIdial, specifically in the vicidial_sales_viewer.php component when password encryption is activated.

As a result, this flaw allows remote attackers to inject and execute arbitrary operating system commands, potentially compromising the web server's security.
