CVE-2022-3732: Critical SQL Injection Vulnerability Discovered in Seccome Ehoney

A critical vulnerability has been discovered in the Seccome Ehoney system, which has been assigned the identifier CVE-2022-3732. This issue affects an unknown function within the /api/v1/bait/set file and has been classified as a SQL injection vulnerability. The VDB-212414 identifier has been assigned to this vulnerability.

The attack can be executed remotely by manipulating the "Payload" argument, leading to the potential compromise of sensitive data, system integrity, or even complete system takeover. This blog post aims to provide an in-depth look at the exploit details, code snippets, and links to original references for better understanding and mitigation.

Exploit Details

The vulnerability can be exploited by an attacker through manipulation of the "Payload" argument, leading to a SQL injection. SQL injection is a web security vulnerability that allows an attacker to interfere with queries an application makes to its database. It generally occurs when an attacker submits malicious SQL statements instead of regular data, which then gets executed by the database.

The affected unknown function within the /api/v1/bait/set file does not properly sanitize the "Payload" input, effectively allowing an attacker to inject malicious SQL code. This vulnerability is classified as critical since it allows an attacker to perform unauthorized actions on the database, such as exfiltrating, modifying, or deleting data, or even gaining administrative privileges.

Code Snippet

The following code snippet demonstrates how the "Payload" argument is handled within the affected file without proper input sanitization:

def set_bait(request):
    if request.method == 'POST':
        payload = request.POST['Payload']
        conn = create_connection()
        with conn.cursor() as cursor:
            sql = "INSERT INTO bait (payload) VALUES ('%s')" % payload
            cursor.execute(sql)
        conn.commit()
    ...

In the above example, the "Payload" value retrieved from the HTTP POST request is directly used in the SQL statement without any sanitization or validation checks, which allows an attacker to inject SQL code, like the following example:

Payload: '); DROP TABLE bait;--

This injected code would cause the "bait" table to be deleted from the database when the query is executed.

- Vulnerability Database Entry: https://vulners.com/nessus/VDB-212414

Update Seccome Ehoney to the latest version, which contains a patch for the vulnerability.

2. Implement input validation and sanitization for the "Payload" argument before using it in SQL queries.
3. Utilize stored procedures and prepared statements within the SQL code, which eliminates the possibility of SQL injection.

Conclusion

The CVE-2022-3732 vulnerability found in Seccome Ehoney poses a critical risk due to its potential to be exploited for SQL injection attacks. It is crucial to apply the necessary mitigations to ensure the security of sensitive data and system integrity. Keep your software up-to-date, validate and sanitize user inputs, and follow secure coding practices to minimize the chances of such vulnerabilities in your systems.
