CVE-2025-56749

Comprehensive Technical Analysis of CVE-2025-56749

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-56749 CISA Vulnerability Name: CVE-2025-56749 CVSS Score: 9.4

The vulnerability in Creativeitem Academy LMS up to and including version 6.14 involves the use of a hardcoded default JWT (JSON Web Token) secret for token signing. This predictable secret allows attackers to forge valid JWT tokens, leading to authentication bypass and unauthorized access to any user account.

Severity Evaluation: The CVSS score of 9.4 indicates a critical vulnerability. This high score is due to the potential for complete authentication bypass, which can result in unauthorized access to sensitive information and potential takeover of user accounts.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Token Forgery: An attacker can craft a valid JWT token using the known default secret, allowing them to impersonate any user.
2. Authentication Bypass: By forging a JWT token, an attacker can bypass authentication mechanisms and gain unauthorized access to user accounts.
3. Privilege Escalation: Once authenticated, the attacker can escalate privileges to access administrative functions or sensitive data.

Exploitation Methods:

1. Reconnaissance: Identify the version of Creativeitem Academy LMS in use.
2. Token Crafting: Use the known default JWT secret to create a valid token.
3. Authentication Bypass: Submit the forged token to the LMS to gain unauthorized access.
4. Data Exfiltration: Access and exfiltrate sensitive data from user accounts.

3. Affected Systems and Software Versions

Affected Systems:

• Creativeitem Academy LMS versions up to and including 6.14.

Software Versions:

• All versions of Creativeitem Academy LMS from the initial release up to version 6.14 are affected.

4. Recommended Mitigation Strategies

Immediate Actions:

1. Patching: Upgrade to a version of Creativeitem Academy LMS that addresses this vulnerability.
2. Secret Rotation: Change the JWT secret to a strong, unique value and ensure it is not hardcoded.
3. Monitoring: Implement monitoring to detect unusual authentication activities or token usage patterns.

Long-Term Strategies:

1. Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
2. Secure Coding Practices: Ensure that secrets and sensitive information are not hardcoded in the application.
3. User Education: Educate users about the importance of strong authentication practices and the risks of using default settings.

5. Impact on Cybersecurity Landscape

Broader Implications:

• Authentication Security: Highlights the importance of secure JWT implementation and the risks associated with hardcoded secrets.
• Vendor Responsibility: Emphasizes the need for vendors to prioritize security in their software development lifecycle.
• User Trust: Undermines user trust in the security of educational platforms, potentially leading to a shift towards more secure alternatives.

Industry Trends:

• Increased Scrutiny: Likely to result in increased scrutiny of educational software for similar vulnerabilities.
• Regulatory Compliance: May prompt regulatory bodies to enforce stricter security standards for educational software.

6. Technical Details for Security Professionals

JWT Token Structure:

• Header: Contains metadata about the type of token and the signing algorithm being used.
• Payload: Contains the claims (user data).
• Signature: Ensures that the token has not been altered.

Vulnerability Specifics:

• The default JWT secret is hardcoded, making it predictable and easily exploitable.
• Attackers can use tools like jwt.io to decode and forge tokens using the known secret.

Detection and Response:

1. Log Analysis: Analyze authentication logs for unusual patterns or repeated failed attempts.
2. Intrusion Detection Systems (IDS): Implement IDS to detect and alert on suspicious token usage.
3. Incident Response Plan: Develop and maintain an incident response plan to quickly address any detected exploitation attempts.

Conclusion: CVE-2025-56749 represents a critical vulnerability in Creativeitem Academy LMS that underscores the importance of secure authentication practices. Immediate patching and long-term security enhancements are essential to mitigate the risks associated with this vulnerability. Organizations should prioritize regular security audits and adhere to best practices in secure coding to prevent similar issues in the future.
