CVE-2025-11200

Comprehensive Technical Analysis of CVE-2025-11200

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-11200 Description: MLflow Weak Password Requirements Authentication Bypass Vulnerability CVSS Score: 9.8

The vulnerability in MLflow, identified as CVE-2025-11200, is classified as a critical security flaw due to its high CVSS score of 9.8. This score indicates a severe risk, primarily because it allows remote attackers to bypass authentication mechanisms. The root cause of this vulnerability is the implementation of weak password requirements, which can be exploited to gain unauthorized access to the system.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can exploit this vulnerability over the network without needing to be physically present.
• Authentication Bypass: The weak password requirements make it easier for attackers to guess or brute-force passwords, thereby bypassing authentication.

Exploitation Methods:

• Brute-Force Attacks: Attackers can use automated tools to try multiple password combinations until they find a valid one.
• Dictionary Attacks: Using a predefined list of common passwords to attempt to gain access.
• Credential Stuffing: Using previously leaked credentials from other breaches to attempt to log in.

3. Affected Systems and Software Versions

Affected Software:

• MLflow versions prior to the patch commit 1f74f3f24d8273927b8db392c23e108576936c54.

Systems:

• Any system running the affected versions of MLflow, including but not limited to, cloud-based deployments, on-premises servers, and development environments.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the patch provided in the commit 1f74f3f24d8273927b8db392c23e108576936c54 to strengthen password requirements.
• Password Policies: Implement strong password policies that enforce complexity, length, and regular updates.
• Multi-Factor Authentication (MFA): Enable MFA to add an additional layer of security.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
• User Education: Educate users on the importance of strong passwords and the risks associated with weak passwords.
• Monitoring: Implement monitoring tools to detect and respond to suspicious login attempts.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-11200 highlights the importance of robust authentication mechanisms and the potential risks associated with weak password policies. This vulnerability underscores the need for continuous security assessments and the implementation of best practices in password management. Organizations should prioritize security hygiene, including regular updates and patches, to mitigate such risks.

6. Technical Details for Security Professionals

Vulnerability Details:

• The vulnerability is rooted in the password handling mechanism of MLflow, where weak password requirements allow for easy exploitation.
• The flaw can be exploited without requiring any authentication, making it a high-risk vulnerability.

Detection:

• Log Analysis: Monitor authentication logs for unusual patterns or repeated failed login attempts.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on brute-force or dictionary attacks.

Response:

• Incident Response Plan: Develop and maintain an incident response plan to quickly address any detected exploitation attempts.
• Forensic Analysis: Conduct forensic analysis to understand the scope and impact of any successful exploitation.
