CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL injection flaw in ESAFENET CDG up to version 20260615. It exists in the file /CDGServer3/ukey/usbkey;logindojojs where the argument keyid can be manipulated to inject malicious SQL code. The attack can be executed remotely and an exploit is publicly available.

Detection Guidance

This vulnerability involves SQL injection in ESAFENET CDG via the /CDGServer3/ukey/usbkey;logindojojs endpoint. To detect it, monitor network traffic for suspicious SQL queries targeting this path. Check server logs for unusual input in the 'keyid' parameter. Use tools like SQLMap to test for injection flaws by sending crafted inputs to the affected endpoint.

Impact Analysis

This vulnerability allows attackers to execute arbitrary SQL commands on the database. This could lead to unauthorized data access, data manipulation, or deletion. Sensitive information like user credentials or application data may be compromised. The remote nature of the attack increases the risk as it can be exploited without physical access.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized data access or breaches. GDPR requires protection of personal data and breach notification, while HIPAA mandates safeguards for protected health information. A successful exploit may result in regulatory penalties, legal liabilities, and reputational damage.

Mitigation Strategies

Immediately restrict network access to the vulnerable ESAFENET CDG server component. Disable or remove the affected file /CDGServer3/ukey/usbkey;logindojojs if possible. Apply input validation to sanitize the keyid parameter to prevent SQL injection. Monitor for unusual database queries or unauthorized access attempts.
