Q-Free MaxTime, Missing Authorization Vulnerability, CVE-2025-26369 Critical

How the CVE Works:

CVE-2025-26369 is a critical vulnerability in Q-Free MaxTime versions 2.11.0 and earlier. It stems from a Missing Authorization CWE-862 flaw in the `maxprofile/user-groups/routes.lua` file. An authenticated attacker with low privileges can exploit this vulnerability by sending crafted HTTP requests to escalate privileges for user groups. This allows unauthorized access to sensitive functionalities, potentially leading to full system compromise. The issue arises due to insufficient validation of user permissions when handling group privilege modifications.

DailyCVE Form:

Platform: Q-Free MaxTime
Version: <= 2.11.0
Vulnerability: Missing Authorization
Severity: Critical
Date: 02/12/2025

What Undercode Say:

Exploitation:

Crafting HTTP Requests: Attackers can use tools like `curl` or `Postman` to send malicious HTTP requests to the `/maxprofile/user-groups` endpoint.
```
curl -X POST -H "Content-Type: application/json" -d '{"group":"admin","privileges":"all"}' http://target/maxprofile/user-groups
```
Privilege Escalation: By manipulating the `group` and `privileges` parameters, attackers can grant themselves or others elevated permissions.

Protection:

Patch Application: Upgrade to the latest version of Q-Free MaxTime beyond 2.11.0.
Input Validation: Implement strict input validation and authorization checks in the `routes.lua` file.
```
if not isAuthorizeduser, "modify_group_privileges" then
return error"Unauthorized"
end
```
Network Segmentation: Restrict access to the `/maxprofile/user-groups` endpoint to trusted IPs.
Log Monitoring: Enable detailed logging for privilege modification attempts.
```
log"Privilege modification attempt by user: " .. user
```
