CVE-2022-29482Network attack vector

Encrypted traffic interception via improper certificate validation

Published Jun 14, 2022 · Updated Aug 3, 2024

Improper certificate validation in DeNA Mobaoku before 5.5.16 allows man-in-the-middle attackers to intercept encrypted app communications. The app's TLS client improperly validates the server certificate; public materials do not identify the affected code or exact failed check. Exploitation requires a malicious wireless access point in the traffic path and permits eavesdropping on app communications.
