Quick.CMS vulnerabilities

Quick.CMS 6.7 contains a SQL injection vulnerability that allows unauthenticated attackers to bypass login authentication by manipulating the login form. Attackers can inject specific SQL payloads like ' or '1'='1 to gain unauthorized administrative access to the system.

A Blind SQL injection vulnerability has been identified in Quick.CMS. Improper neutralization of input provided by a high-privileged user into multiple fields in the administration panel allows for Blind SQL Injection attacks. The vendor states that remediation was not deemed necessary due to the trust model.

Quick.CMS is vulnerable to Path Traversal via the URI path component of HTTP requests. An authenticated attacker with admin privileges can read files in the parent directory of the webroot using ../ sequences in the URI.

Quick.CMS is vulnerable to Local File Inclusion (LFI) in the admin.php endpoint via the p parameter. An authenticated attacker with admin privileges can include arbitrary files within the application's directory structure, revealing directory structure and absolute paths.

In Quick.CMS, the admin UI restricts deletion of the primary language, but the API endpoint lacks server-side authorization. An authenticated admin can send a direct HTTP request to delete the primary language, causing Denial of Service (DoS). Combined with a CSRF vulnerability (CVE-2026-1468), an unauthenticated attacker can trick an admin into clicking a malicious link, triggering DoS.

Quick.CMS deserializes user-controlled data received over plaintext HTTP without ensuring integrity or authenticity. Attackers can tamper with serialized payloads in transit and inject malicious objects, leading to remote code execution. Exploitation is triggered automatically when an administrator accesses the admin panel.
