Password-pattern disclosure via reused AES-CFB key and IV
Published Feb 17, 2025 · Updated Feb 19, 2025
Weak password storage in Mobatek MobaXterm before 25.0 allows local users to infer saved-password patterns from encrypted data. The password-encryption module reuses one master-key derivative and an all-zero IV for every AES-CFB ciphertext, making equal passwords produce equal ciphertext. Exploitation requires access to encrypted saved passwords; it reveals password reuse and known prefixes and supports chosen-plaintext attacks.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
