CVE Alert: CVE-2023-32251
Vulnerability Summary: CVE-2023-32251
A vulnerability has been identified in the Linux kernel’s ksmbd component (kernel SMB/CIFS server). A security control designed to prevent dictionary attacks, which introduces a 5-second delay during session setup, can be bypassed through the use of asynchronous requests. This bypass negates the intended anti-brute-force protection, potentially allowing attackers to conduct dictionary attacks more efficiently against user credentials or other authentication mechanisms.
