A significant security vulnerability, identified as CVE-2024-55580, was discovered in Qlik Sense Enterprise for Windows, a popular business intelligence and data visualization platform. The affected versions include all releases before November 2024 IR. This vulnerability poses a threat to the system's availability, integrity, and confidentiality, and must be addressed immediately to prevent potential damages.

Exploit Details

The vulnerability allows unprivileged users with network access to execute remote commands on the Qlik Sense Enterprise servers. As a result, an attacker may disrupt the server, compromise sensitive data, and make unauthorized changes to the system configuration.

The following code snippet demonstrates the improper handling of user input, which could potentially be exploited to execute malicious commands:

var userInput = req.body.input;
var exec = require('child_process').exec;
exec('qlik-cli ' + userInput, function (error, stdout, stderr) {
    ...
});

In this example, the userInput variable is directly concatenated to a command string, which, in turn, is executed via the exec function. An attacker could craft a malicious input and pass it to this command, leading to arbitrary command execution.
