• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal complexity.
• Privileges Required (PR): Low (L) - The attacker needs low-level privileges to exploit the vulnerability.
• User Interaction (UI): Required (R) - The attack requires some form of user interaction.
• Scope (S): Changed (C) - The vulnerability affects a different security scope.
• Confidentiality (C): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability has a high impact on integrity.
• Availability (A): High (H) - The vulnerability has a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through the dataset upload functionality. An attacker can exploit this vulnerability by:

• Crafting Malicious HTTP Requests: The attacker can send specially crafted HTTP requests that include malicious HTML code.
• User Interaction: The attacker may need to trick a user into performing an action, such as uploading a dataset or clicking a link, to trigger the malicious code.
• Session Hijacking: Once the malicious code is executed, the attacker can hijack user sessions, steal sensitive information, or perform actions on behalf of the user.

3. Affected Systems and Software Versions

The vulnerability specifically affects:

• ClearML Enterprise Server version 3.22.5-1533.

Other versions of ClearML Enterprise Server may also be affected, but this has not been confirmed. Organizations using this version should prioritize patching or implementing mitigation strategies.
