TLS traffic interception via missing certificate validation
Published Jun 22, 2020 · Updated Aug 4, 2024
Improper certificate validation in Sophos Secure Email 3.9.4 and earlier for Android allows man-in-the-middle attackers to intercept TLS traffic. The application's TLS connection path accepts a server certificate without performing the required trust validation, allowing an attacker-controlled endpoint to impersonate the mail server. Exploitation requires control of the network path and a forged certificate; the published assessment limits the reported impact to confidentiality.
