CVE-2020-35138
The MobileIron agents through 2021-03-22 for Android and iOS contain a hardcoded encryption key, used to encrypt the submission of username/password details during the authentication process, as demonstrated by Mobile@Work (aka com.mobileiron).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
