CVE-2025-50870 in Institute-of-Current-Students
Summary
by MITRE • 08/01/2025
Institute-of-Current-Students 1.0 is vulnerable to Incorrect Access Control in the mydetailsstudent.php endpoint. The myds GET parameter accepts an email address as input and directly returns the corresponding student's personal information without validating the identity or permissions of the requesting user. This allows any authenticated or unauthenticated attacker to enumerate and retrieve sensitive student details by altering the email value in the request URL, leading to information disclosure.

The vulnerability identified as CVE-2025-50870 affects Institute-of-Current-Students version 1.0 and represents a critical access control flaw in the mydetailsstudent.php endpoint. This weakness stems from inadequate input validation and authentication checks that permit unauthorized data retrieval through manipulation of the myds GET parameter. The system fails to implement proper authorization mechanisms, allowing attackers to exploit the endpoint by simply modifying the email address parameter in the request URL. The vulnerability directly violates fundamental security principles by exposing sensitive student personal information without verifying the identity or privileges of the requesting entity, creating a significant risk for privacy and data protection.
The technical implementation of this flaw demonstrates a classic case of insufficient access control validation where the application assumes that legitimate users will only request information for themselves. The myds GET parameter accepts arbitrary email addresses and processes them without performing any verification against the current user session or authentication context. This design flaw enables what security researchers categorize as improper authorization within the context of CWE-285, which specifically addresses issues where applications fail to properly enforce access control mechanisms. The vulnerability operates at the application layer and can be exploited through simple URL manipulation techniques, making it particularly dangerous as it requires minimal technical expertise to exploit.
From an operational impact perspective, this vulnerability creates a substantial risk for student privacy and institutional data protection. Attackers can systematically enumerate student records by iterating through email addresses, potentially obtaining personal information including names, contact details, academic records, and other sensitive data. The information disclosure risk extends beyond individual privacy concerns to potential identity theft, social engineering attacks, and compliance violations with data protection regulations such as gdpr andFERPA. The vulnerability affects both authenticated and unauthenticated attackers, significantly broadening the attack surface and reducing the barrier to exploitation. This weakness represents a critical gap in the security architecture that could lead to cascading effects if combined with other vulnerabilities or if the exposed data is used for further attacks within the system.
Mitigation strategies for CVE-2025-50870 must focus on implementing proper access control validation and authentication checks. The system should verify that the requesting user has legitimate authorization to access the specified student information, typically by comparing the requested email address against the authenticated user's identity or implementing role-based access controls. Input validation should be strengthened to ensure that the myds parameter cannot be arbitrarily manipulated to access unauthorized records. Organizations should implement the principle of least privilege, ensuring that users can only access information relevant to their own authenticated identity or roles. Additionally, the application should log access attempts and implement rate limiting to prevent automated enumeration attacks. This vulnerability aligns with ATT&CK technique T1213.002 which covers data from information repositories, and organizations should consider implementing defensive measures such as web application firewalls and security monitoring to detect and prevent exploitation attempts. The fix requires immediate attention and should be prioritized alongside other critical security vulnerabilities to prevent potential data breaches and maintain regulatory compliance.
