Executive Summary

CVE-2018-25185 is an SQL injection vulnerability in Wecodex Restaurant CMS version 1.0. It allows unauthenticated attackers to inject malicious SQL code through the username parameter in the login POST request. This happens because the application does not properly sanitize or parameterize the username input before including it in SQL queries.

Attackers can exploit this vulnerability using boolean-based blind SQL injection techniques, which infer information based on true or false conditions, or time-based blind SQL injection techniques, which use delays to confirm the presence of the vulnerability. These methods enable attackers to manipulate database queries and extract sensitive information from the backend database.

Impact Analysis

Exploitation of this SQL injection vulnerability can lead to unauthorized access to the administrative dashboard of the Wecodex Restaurant CMS. Attackers may gain access without authentication by manipulating the login process.

Additionally, attackers can extract sensitive database information, modify data, or further exploit underlying database vulnerabilities. This can result in data leakage, data integrity issues, and potential compromise of the entire backend system.

Detection Guidance

This vulnerability can be detected by sending crafted POST requests to the login endpoint that include malicious SQL payloads in the username parameter. Detection involves testing for SQL injection using boolean-based blind or time-based blind SQL injection techniques.

For example, you can test boolean-based blind SQL injection by sending a POST request with a payload like: username=admin" RLIKE (SELECT (CASE WHEN (7084=7084) THEN 0x61646d696e4061646d696e2e636f6d ELSE 0x28 END)) AND "eloY"="eloY". If the response differs based on the injected condition, the vulnerability is present.

Alternatively, time-based blind SQL injection can be tested by sending a payload such as: username=admin" AND (SELECT * FROM (SELECT(SLEEP(5)))lzxm) AND "vZea"="vZea". If the server response is delayed by the sleep time, it indicates the vulnerability.

These tests can be performed using tools like curl or specialized SQL injection testing tools on Kali Linux or similar environments.

Mitigation Strategies

Immediate mitigation steps include implementing proper input validation and sanitization on the username parameter in the login functionality to prevent SQL injection.

Use parameterized queries or prepared statements in the backend code to ensure that user input is not directly embedded into SQL queries.

Restrict access to the login endpoint and monitor for suspicious POST requests that may indicate exploitation attempts.

If possible, update or patch the Wecodex Restaurant CMS to a version that addresses this vulnerability or apply custom fixes to sanitize inputs.
