This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Visual Voice Mail (VVM) application through 2022-02-24 for Android allows persistent access if an attacker temporarily controls an application that has the READ_SMS permission, and reads an IMAP credentialing message that is (by design) not displayed to the victim within the AOSP SMS/MMS messaging application. (Often, the IMAP credentials are usable to listen to voice mail messages sent before the vulnerability was exploited, in addition to new ones.) NOTE: some vendors characterize this as not a "concrete and exploitable risk.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
