Online Notice Board EUVD-2025-16982

Real-world risk is substantial despite CVSS 7.3 (which underrepresents severity): (1) Attack Vector is Network/Unauthenticated (AV:N/PR:N) - lowest barrier to entry; (2) Attack Complexity is Low (AC:L) - no special conditions required; (3) Confidentiality, Integrity, and Availability impacts are all partial (C:L/I:L/A:L) - understates SQL injection potential for full database compromise; (4) Public POC availability dramatically increases exploitation likelihood - this is not theoretical; (5) No authentication required means any internet-connected attacker can exploit immediately. The discrepancy between CVSS scoring and actual risk suggests this should be treated as critical priority. Organizations cannot rely on the 7.3 score alone - SQL injection on unauthenticated registration endpoints historically sees rapid, mass exploitation. The vulnerability's presence in a registration module indicates potential for account takeover, privilege escalation, and data breach scenarios.

An attacker discovers the application's registration page at /register.php. They craft a malicious payload in the fname field such as: John' OR '1'='1 or John'; DROP TABLE users;-- and submit the registration form. Due to lack of input sanitization, this payload is directly concatenated into a SQL query like INSERT INTO users (fname, ...) VALUES ('John' OR '1'='1', ...), causing unintended SQL logic execution. The attacker can: (1) bypass authentication to enumerate valid usernames; (2) extract sensitive data from the database (credentials, personal information, notices); (3) modify or delete database records; (4) potentially execute OS commands if database user has FILE privileges. With public POC availability, automated scanning tools can identify vulnerable instances at scale, leading to mass exploitation campaigns. An attacker requires only a web browser and network access—no special tools or insider knowledge needed.
