How the Exploit Works
The vulnerability occurs due to improper neutralization of special elements used in an SQL command within the GoodLayers Hostel application. This allows an attacker to inject malicious SQL code into the application, which is then executed by the database. This type of attack, known as Blind SQL Injection, is particularly dangerous as it does not require any user interaction and can be performed remotely over the network.
Conceptual Example Code
An example of how the vulnerability might be exploited could look similar to the following HTTP request:
POST /goodlayers/hostel/login HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "username": "admin", "password": "password' OR '1'='1'; -- " }In this example, the malicious SQL code `’ OR ‘1’=’1′; –` is inserted into the password field. This code would bypass the login authentication, granting the attacker administrative access to the application.
Mitigation Guidance
Users of affected versions of GoodLayers Hostel are urged to apply the vendor patch as soon as possible. If unable to immediately apply the patch, users should implement a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. These solutions can help detect and block SQL Injection attacks until the vendor patch can be applied. However, they should not be considered a long-term solution as they do not address the underlying vulnerability.
