Deeper analysis
CVE-2024-33610 affects certain Sharp and Toshiba multifunction printer and copier devices. The pages sessionlist.html and sys_trayentryreboot.html can be reached without any authentication, exposing session cookies of logged-in users via the first page and permitting arbitrary device reboots via the second. The issue is tracked under CWE-288 and carries a CVSS 3.1 score of 9.1.
An unauthenticated attacker with network access can retrieve active session tokens, enabling impersonation of legitimate users, or trigger a reboot to disrupt device availability. No credentials or user interaction are required for either action.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.
Users can identify logons via alternate paths or channels by reviewing the previous logon time.
Adaptive requirements can apply across access paths, reducing the ability to bypass authentication via alternate channels or paths.
Centralized IdPs close alternate authentication paths that enable bypass.
Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.
Requires authentication to occur exclusively over the isolated trusted path, directly preventing bypass via alternate or untrusted channels.
