Information disclosure via improper certificate validation
Published Apr 11, 2022 · Updated Aug 3, 2024
Improper certificate validation in MediaTek A-GPS allows remote attackers to disclose information through a man-in-the-middle attack. The A-GPS client improperly validates the server certificate, allowing an intermediary to intercept information exchanged with the service. Exploitation requires a man-in-the-middle position but no privileges or user interaction, and the reported impact is limited to information disclosure.
