Comprehensive Technical Analysis of CVE-2024-24496

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-24496 CISA Vulnerability Name: CVE-2024-24496 CVSS Score: 9.8

The vulnerability in Daily Habit Tracker v.1.0 allows a remote attacker to manipulate trackers via the home.php, add-tracker.php, delete-tracker.php, and update-tracker.php components. The CVSS score of 9.8 indicates a critical severity level, suggesting that this vulnerability poses a significant risk to the affected systems. The high score is likely due to the potential for unauthorized access, data manipulation, and the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

The vulnerability is classified as a Broken Access Control issue, which typically involves the following attack vectors:

• Unauthorized Access: An attacker can access and manipulate trackers without proper authentication or authorization.
• Data Manipulation: The attacker can add, delete, or update trackers, leading to data integrity issues.
• Privilege Escalation: If the application has different user roles, an attacker could potentially escalate privileges to perform actions reserved for higher-privileged users.

Exploitation Methods:

• Direct URL Manipulation: An attacker can directly manipulate URL parameters to perform unauthorized actions.
• Cross-Site Request Forgery (CSRF): An attacker can trick authenticated users into performing actions they did not intend to perform.
• SQL Injection: If input validation is lacking, an attacker could inject malicious SQL queries to manipulate the database.

3. Affected Systems and Software Versions

Affected Software: Daily Habit Tracker v.1.0 Components: home.php, add-tracker.php, delete-tracker.php, update-tracker.php

All systems running Daily Habit Tracker v.1.0 are affected. It is crucial to identify and update these systems to mitigate the risk.

4. Recommended Mitigation Strategies

1. Patch Management: Immediately apply any available patches or updates from the vendor.
2. Access Controls: Implement robust access control mechanisms to ensure that only authorized users can perform actions on trackers.
3. Input Validation: Enforce strict input validation and sanitization to prevent SQL injection and other injection attacks.
4. Authentication and Authorization: Ensure that all actions require proper authentication and authorization checks.
5. Monitoring and Logging: Implement comprehensive logging and monitoring to detect and respond to any suspicious activities.
6. Regular Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security issues.
