XPath injection

XPath Boolean-Based Injection is a sophisticated technique employed to bypass the authentication mechanisms of web applications. This method manipulates the query logic by injecting conditions that invariably return true, thereby tricking the application into granting access without the requisite authentication credentials.

• Unauthorized access to sensitive data
• Data modification or deletion
• System compromise
• Denial of Service
• Reputation damage
• Compliance violations

The issue can be found on the server side.

To mitigate the risk of XPath error-based injection vulnerabilities, it is crucial to meticulously manage and sanitize user input, rigorously verify XPath queries, and establish robust error-handling protocols. Implementing stringent input validation and filtering measures is imperative to prevent the ingress of malicious input. Furthermore, error responses must be scrutinized to ensure they do not disclose sensitive information that could aid attackers.
