Summary
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.
Risk Assessment
An attacker can read application source code or configuration files, potentially leading to further attacks.
Recommendation
The vendor does not plan a fix; restrict access to admin.php and monitor logs for suspicious requests.
Other vulnerabilities in Quick.CMS
See all- CVE-2024-58308Critical
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.
- CVE-2026-33385Medium
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.
- CVE-2026-63303Medium
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.
- CVE-2026-63301High
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.
- CVE-2026-11860High
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.
Original NVD description (English source)
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 located within the application's directory structure via a crafted HTTP request. Successful exploitation allows disclosure of the server's directory structure and absolute file paths (path disclosure). The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
