Information disclosure via mishandled cryptographic initialization vectors
Published Jan 21, 2020 · Updated Aug 5, 2024
Information disclosure in Huawei USG9500 firmware allows attackers with access to a cryptographic primitive to weaken its confidentiality. The firmware improperly processes the initialization vector used by an unspecified encryption algorithm, reducing the confidentiality associated with that primitive. Exploitation requires access to the cryptographic primitive; Huawei does not identify the algorithm, exposed interface, or recoverable plaintext or key material.

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.
