Overview
Today, we dive deep into the CVE-2025-51535, a severe SQL injection vulnerability discovered in the Austrian Archaeological Institute’s OpenAtlas version 8.11.0. This vulnerability primarily affects users and developers of this OpenAtlas system, a platform widely used by archaeologists and researchers worldwide. It’s a critical concern due to the potential for unauthorized system compromise and data leakage, which can lead to significant damage, including loss of intellectual property and sensitive data.

How the Exploit Works
SQL Injection is a code injection technique that attackers can use to insert malicious SQL statements into an entry field for execution. In the case of CVE-2025-51535, the attacker could exploit the vulnerability by sending specially crafted requests to the OpenAtlas application, which fails to properly sanitize user-supplied input.
The application’s failure to effectively sanitize input allows an attacker to inject arbitrary SQL commands, which are then executed by the database. This could lead to unauthorized read and write access to the database, potential system compromise, and data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This example represents an HTTP request that an attacker might send to exploit the vulnerability.
POST /openatlas/login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin' OR '1'='1'; -- &password=1234In the above example, the attacker sends a crafted payload through the username field in the login request. The injected SQL command ‘OR ‘1’=’1′ will always evaluate to true, causing the SQL query to return all rows from the table, allowing the attacker to bypass the login mechanism.
Mitigation
To mitigate this vulnerability, users of OpenAtlas version 8.11.0 are advised to apply the patch provided by the vendor immediately. As a temporary measure, users could also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) configured to detect and block SQL Injection attacks. However, this should not replace the need for applying the official patch to fix the underlying vulnerability permanently.
