SQL Injection Vulnerabilities in Centreon CVE-2024-39843, CVE-2024-39842

 SQL Injection Vulnerabilities in Centreon 

Centreon, a widely used network and application monitoring tool, has recently been identified as having multiple SQL injection vulnerabilities, specifically CVE-2024-39843 and CVE-2024-39842. These vulnerabilities allow authenticated high-privileged attackers to execute arbitrary SQL commands, posing significant risks to the integrity and security of the systems utilizing Centreon.

Details of Vulnerabilities

CVE-2024-39843

This vulnerability is found in Centreon version 24.04.2, affecting the "create user" form inputs. It allows a remote attacker with high privileges to inject malicious SQL commands into the system. The lack of proper input validation enables attackers to manipulate SQL queries executed by the database.Example of Exploitation:
An attacker could use a crafted input in the "create user" form that includes SQL commands. For instance, if the input field for a username is not properly sanitized, an attacker might input:

sql
' OR 1=1; DROP TABLE users; --

This command could potentially drop the users table if executed without proper safeguards in place, leading to data loss and service disruption.

CVE-2024-39842

Similar to CVE-2024-39843, this vulnerability also exists in Centreon 24.04.2 but pertains to "user massive changes" inputs. This flaw allows attackers to execute arbitrary SQL commands through bulk user modification forms.Example of Exploitation:
An attacker could exploit this vulnerability by submitting a payload that alters multiple user records simultaneously. For example:

sql
1); INSERT INTO users (username, password) VALUES ('attacker', 'password'); --

If executed, this command would create a new user with administrative privileges, compromising the system's security.

Technical Analysis

Both vulnerabilities stem from insufficient input validation and sanitization within the web application's forms. When user inputs are directly incorporated into SQL queries without adequate checks, it opens pathways for SQL injection attacks.

Attack Vector

1. Authentication Required: Attackers must first authenticate as high-privileged users to exploit these vulnerabilities.
2. Crafting Malicious Payloads: Using tools like Burp Suite or custom scripts, attackers can craft specific payloads targeting vulnerable fields.
3. Submitting Malicious Requests: The attacker submits these payloads through the affected forms in Centreon's web interface.

Mitigation Strategies

To mitigate these vulnerabilities:

• Input Validation: Implement strict validation rules on all user inputs to ensure they conform to expected formats.
• Parameterized Queries: Use prepared statements or parameterized queries to separate SQL logic from data inputs.
• Regular Updates: Keep Centreon updated with the latest security patches and versions that address known vulnerabilities.

Conclusion

The identified SQL injection vulnerabilities (CVE-2024-39843 and CVE-2024-39842) in Centreon highlight critical security risks that can be exploited by high-privileged attackers. Organizations using Centreon should take immediate steps to patch their systems and enhance their security measures against such vulnerabilities to protect their data and maintain service integrity.
