CVE-2025-50870

Comprehensive Technical Analysis of CVE-2025-50870

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-50870 Description: The Institute-of-Current-Students 1.0 application is vulnerable to Incorrect Access Control in the mydetailsstudent.php endpoint. The myds GET parameter accepts an email address as input and returns the corresponding student's personal information without proper validation of the requesting user's identity or permissions.

CVSS Score: 9.8 Severity: Critical

Assessment:

• Confidentiality Impact: High
• Integrity Impact: None
• Availability Impact: None
• Exploitability: High
• Remediation Level: Official-Fix

The high CVSS score of 9.8 indicates a critical vulnerability due to the potential for unauthorized access to sensitive information, which can lead to significant data breaches and privacy violations.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker can exploit this vulnerability without needing to authenticate, making it highly accessible.
• Enumeration: By altering the email value in the request URL, an attacker can systematically enumerate and retrieve personal information for multiple students.

Exploitation Methods:

• Direct URL Manipulation: An attacker can craft URLs with different email addresses to retrieve corresponding student details.
• Automated Scripts: Attackers can use automated scripts to iterate through a list of known email addresses, collecting sensitive information en masse.

3. Affected Systems and Software Versions

Affected Software:

• Institute-of-Current-Students 1.0

Affected Endpoint:

• mydetailsstudent.php

Affected Parameter:

• myds GET parameter

Note: All deployments of Institute-of-Current-Students 1.0 are affected unless specific mitigations have been applied.

4. Recommended Mitigation Strategies

Immediate Mitigations:

• Access Control: Implement proper access control mechanisms to validate the identity and permissions of the requesting user before returning any student information.
• Input Validation: Ensure that the myds parameter is validated and that only authorized users can access the endpoint.
• Rate Limiting: Implement rate limiting to prevent automated scripts from rapidly querying the endpoint.

Long-Term Mitigations:

• Patching: Apply the official patch or update provided by the software vendor.
