CyberRota Analysis
AI-GeneratedRejetto HFS versions 3.0.0 to 3.2.0 are vulnerable due to the use of a non-cryptographic random number generator for session-cookie signing, which exposes its outputs to unauthenticated users during login. This flaw allows remote attackers to collect login responses, reconstruct the generator's state, and forge a valid administrator session cookie, potentially leading to full administrative access and remote code execution. Organizations using affected versions should prioritize this vulnerability to mitigate the risk of unauthorized access and exploitation.

Original NVD Description
Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random() generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's state, recover the signing key, and forge a valid administrator session cookie, leading to full administrative access and remote code execution via the server_code configuration feature.
