Published Sep 3, 2024CWE-261EPSS 0.09%

Overview

CVE-2024-45394 is a high-severity vulnerability. It was published on September 3, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

Authenticator is a browser extension that generates two-step verification codes. In versions 7.0.0 and below, encryption keys for user data were stored encrypted at-rest using only AES-256 and the EVP_BytesToKey KDF. Therefore, attackers with a copy of a user's data are able to brute-force the user's encryption key. Users on version 8.0.0 and above are automatically migrated away from the weak encoding on first login. Users should destroy encrypted backups made with versions prior to 8.0.0.

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.
