CVE-2020-36945

8.2

WebDamn · User Registration and Login System

The WebDamn User Registration and Login System is vulnerable to SQL injection, allowing unauthenticated attackers to bypass authentication by manipulating input in the username and password fields.

Executive summary

A critical SQL injection vulnerability in the WebDamn User Registration and Login System allows unauthenticated attackers to bypass authentication and gain unauthorized access to the user panel.

Vulnerability

The application fails to properly neutralize special elements in SQL commands, specifically within the login function. Unauthenticated attackers can inject SQL payloads into the username and password fields to manipulate database queries and bypass the authentication gate.

Business impact

The ability for an unauthenticated attacker to bypass login controls poses a severe risk to data confidentiality and integrity. Successful exploitation grants unauthorized access to the user panel, potentially leading to unauthorized data access, administrative account compromise, or further exploitation of the underlying database. The CVSS score of 8.2 reflects the high risk associated with this unauthenticated remote access vector.

Remediation

Immediate Action: As no official patch is currently available, administrators should restrict access to the login page via network-level controls or disable the vulnerable registration and login system until a fix is provided by the vendor.

Proactive Monitoring: Review web server and database logs for anomalous input patterns, specifically looking for SQL syntax characters such as single quotes, OR clauses, and tautological statements like 1=1 in authentication requests.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block common SQL injection patterns targeting authentication parameters.

Exploitation status

Public Exploit Available: Yes, a proof-of-concept exploit is available via Exploit-DB (EDB-ID: 49170).

Analyst recommendation

Given the high CVSS score and the public availability of a functional proof-of-concept, this vulnerability presents a significant risk to any environment hosting the affected software. Organizations currently using the WebDamn User Registration and Login System must implement immediate compensating controls or disable the service to prevent unauthorized access, as the lack of a vendor patch necessitates a defensive-first approach.
