CVE-2024-7941 in MicroSCADA SYS600
Summary
by MITRE • 08/27/2024
An HTTP parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials.

This vulnerability represents a critical server-side request forgery issue that enables attackers to manipulate HTTP parameters containing URL values, potentially leading to unauthorized redirects and credential theft. The flaw exists within web application logic that fails to properly validate or sanitize URL parameters before processing them, creating an avenue for malicious actors to redirect users to attacker-controlled domains. Such vulnerabilities fall under the CWE-601 category of URL Redirection to Untrusted Site, which is classified as a high-severity security weakness in the Common Weakness Enumeration framework.
The technical implementation of this vulnerability allows attackers to craft malicious HTTP requests where parameter values contain URLs pointing to phishing domains. When the web application processes these parameters without proper validation, it executes the redirect operation, seamlessly transferring users from legitimate sites to malicious ones without user awareness. This behavior directly enables credential harvesting attacks and represents a significant risk to user authentication security. The vulnerability operates at the application layer and can be exploited through various HTTP methods including GET and POST requests, making it particularly dangerous in environments where applications handle user input through web forms or API endpoints.
The operational impact of CVE-2024-7941 extends beyond simple phishing attempts to encompass comprehensive user data compromise and potential system infiltration. Users who unknowingly follow redirects to malicious sites may unknowingly submit credentials to attacker-controlled servers, enabling unauthorized access to accounts and sensitive information. This vulnerability directly aligns with the ATT&CK technique T1566.001 for Phishing and can be leveraged as part of broader attack chains to establish persistent access to target environments. The risk is compounded by the fact that such redirects often appear legitimate to end users, making detection and prevention challenging.
Effective mitigation strategies for this vulnerability require comprehensive input validation and sanitization mechanisms throughout the application stack. Organizations should implement strict URL validation using allowlists of trusted domains and reject any parameter values that do not conform to expected patterns. The implementation of Content Security Policy headers and proper redirect handling mechanisms can significantly reduce exploitation potential. Additionally, security controls should include monitoring for suspicious redirect patterns and implementing proper logging of redirect operations to detect potential abuse. Regular security assessments and code reviews focusing on parameter handling and URL processing functions are essential to prevent similar vulnerabilities from emerging in future application versions.
