Comprehensive Technical Analysis of CVE-2024-35353

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-35353 CVSS Score: 9.8

The vulnerability in Diño Physics School Assistant version 2.3 involves an Insecure Direct Object Reference (IDOR) within the file /classes/Users.php?f=save. This vulnerability allows an attacker to manipulate the id argument, leading to improper authorization. The high CVSS score of 9.8 indicates a critical severity, suggesting that exploitation could result in significant impact, including unauthorized access to sensitive data or system functions.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthorized Access: An attacker could manipulate the id parameter to access or modify user data without proper authorization.
• Data Tampering: By altering the id value, an attacker could potentially change user information, leading to data integrity issues.
• Privilege Escalation: If the id parameter is used to determine user roles or permissions, an attacker could escalate their privileges.

Exploitation Methods:

• Direct Manipulation: An attacker could directly manipulate the id parameter in the URL to access different user accounts.
• Automated Scripts: Attackers could use automated scripts to iterate through possible id values, attempting to access or modify user data.

3. Affected Systems and Software Versions

Affected Software:

• Diño Physics School Assistant version 2.3

Affected Systems:

• Any system running the vulnerable version of Diño Physics School Assistant.
• Systems where the /classes/Users.php?f=save endpoint is exposed and accessible.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor to mitigate the vulnerability.
• Access Controls: Implement strict access controls to ensure that only authorized users can access the /classes/Users.php?f=save endpoint.
• Input Validation: Enforce robust input validation to prevent unauthorized manipulation of the id parameter.

Long-Term Strategies:

• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities.
• Security Training: Provide security training for developers to understand and avoid common vulnerabilities like IDOR.
• Regular Audits: Perform regular security audits and vulnerability assessments to identify and mitigate potential security issues.
