Detailsinfo

A vulnerability, which was classified as very critical, was found in VICIdial up to 2.13 RC1. Affected is the function exec of the file vicidial_sales_viewer.php. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An unauthenticated command injection vulnerability exists in VICIdial versions 2.9 RC1 through 2.13 RC1, within the vicidial_sales_viewer.php component when password encryption is enabled (a non-default configuration). The application improperly passes the HTTP Basic Authentication password directly to a call to exec() without adequate sanitation. This allows remote attackers to inject and execute arbitrary operating system commands as the web server user.
