CVE-2024-51727Network attack vector

Account denial of service via premature session release

Published Dec 6, 2024 · Updated Dec 6, 2024

Premature resource release in Ruijie Networks ReyeeOS 2.206.x before 2.320.x allows remote authenticated users to invalidate sessions. The public advisory identifies a feature that releases a legitimate user session while it is still expected to remain valid, but does not identify the feature or request that triggers the release. Access with low privileges and network reachability are required, and exploitation interrupts only the targeted account session rather than the device or network service.
