Wecodex Hotel CMS 1.0 SQL Injection Vulnerability

Wecodex Hotel CMS 1.0 is susceptible to an SQL injection vulnerability (CVE-2018-25195) within its admin login feature. Discovered in 2026, this flaw enables unauthenticated attackers to inject malicious SQL code into the ‘username’ parameter of a POST request sent to the ‘index.php’ page with the ‘action=processlogin’ parameter. Successful exploitation could lead to the bypass of authentication mechanisms, potentially granting unauthorized administrative privileges. The vulnerability poses a significant risk to organizations utilizing the vulnerable CMS, as attackers could gain full control over the web application and its underlying data, including user credentials and sensitive business information. This requires immediate attention and patching.

Attack Chain

1. An unauthenticated attacker identifies a Wecodex Hotel CMS 1.0 instance.
2. The attacker crafts a malicious SQL payload designed to bypass authentication.
3. The attacker sends a POST request to index.php with the parameter action=processlogin.
4. The crafted SQL payload is injected into the username parameter of the POST request.
5. The application fails to properly sanitize the input, passing the malicious SQL to the database.
6. The injected SQL code manipulates the authentication query, likely using OR clauses and commenting out the rest of the original query.
7. The manipulated query returns a successful authentication result, bypassing the intended login process.
8. The attacker gains unauthorized access to the administrative panel of the Wecodex Hotel CMS.

Impact

Successful exploitation of this SQL injection vulnerability allows attackers to bypass authentication controls and gain administrative access to the Wecodex Hotel CMS 1.0. This can lead to full compromise of the system, including the theft of sensitive data such as customer information, financial records, and proprietary business data. Attackers can also modify the website, inject malicious code, or use the compromised server as a launching point for further attacks. Given the potential for complete system compromise, this vulnerability poses a critical risk to affected organizations.

Recommendation

• Block POST requests to /index.php containing suspicious SQL syntax in the username parameter using a web application firewall (WAF) or intrusion detection system (IDS), based on the provided attack chain.
• Deploy the provided Sigma rule to detect exploitation attempts targeting the login functionality of Wecodex Hotel CMS.
• Upgrade to a patched version of Wecodex Hotel CMS that addresses CVE-2018-25195 if available from the vendor.
• Implement parameterized queries or prepared statements in the application code to prevent SQL injection vulnerabilities.
