BaseFortify

Publication date: 2025-11-18

Last updated on: 2025-11-18

Assigner: MITRE

Description
The openml/openml.org web application version v2.0.20241110 uses predictable MD5-based tokens for critical user workflows such as signup confirmation, password resets, email confirmation resends, and email change confirmation. These tokens are generated by hashing the current timestamp formatted as "%d %H:%M:%S" without incorporating any user-specific data or cryptographic randomness. This predictability allows remote attackers to brute-force valid tokens within a small time window, enabling unauthorized account confirmation, password resets, and email change approvals, potentially leading to account takeover.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability involves the openml/openml.org web application using predictable MD5-based tokens for important user actions like signup confirmation, password resets, and email change confirmations. The tokens are generated by hashing the current timestamp without any user-specific data or randomness, making them predictable. Attackers can brute-force these tokens within a small time window to perform unauthorized actions such as confirming accounts, resetting passwords, or approving email changes.


How can this vulnerability impact me? :

The vulnerability can lead to unauthorized account confirmation, password resets, and email change approvals by attackers who brute-force the predictable tokens. This can result in account takeover, compromising user accounts and potentially leading to loss of access or control over affected accounts.
