What is CVE-2024-37408?
CVE-2024-37408 is a high-severity authentication bypass vulnerability in n/a, published on 8 Jun 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
fprintd through 1.94.3 lacks a security attention mechanism, and thus unexpected actions might be authorized by "auth sufficient pam_fprintd.so" for Sudo. NOTE: the supplier disputes this because they believe issue resolution would involve modifying the PAM configuration to restrict pam_fprintd.so to front-ends that implement a proper attention mechanism, not modifying pam_fprintd.so or fprintd.
Weakness: CWE-287
