CVE-2024-2420Network attack vector

Authentication bypass via hard-coded password

Published May 30, 2024 · Updated Aug 1, 2024

Hard-coded credentials in LenelS2 NetBox 5.6.1 and earlier allow remote attackers to bypass authentication over the network. Carrier identifies a hard-coded password but does not disclose the affected account, authentication endpoint, or credential-validation code path. No prior privileges or user interaction are required, and successful use grants access to functions and data otherwise protected by authentication.
