Published Apr 3, 2025 · Updated Apr 4, 2025

Incorrect default permissions in Huang-yk student-manage 1 allow local users to escalate privileges through unsafe permission verification. The public record does not identify the affected file, directory, permission check, or operation that mishandles access rights. Low-privileged local access is required, and successful exploitation grants access at a higher privilege level.
