Deeper analysis
Zoho ManageEngine Remote Access Plus versions prior to 10.1.2137.15 contain an information disclosure vulnerability tracked as CVE-2022-26777. The flaw, assigned CWE-425, permits guest users to retrieve license details through direct requests, resulting in a CVSS 5.3 rating that reflects network-accessible exposure with no authentication or user interaction required and limited impact to confidentiality.
Unauthenticated remote attackers can exploit the issue by sending crafted requests to the affected Remote Access Plus instance, allowing them to view license information that should be restricted. This grants low-privileged insight into deployment details without any further system compromise.
Vendor advisories from ManageEngine direct administrators to upgrade to version 10.1.2137.15 or later to address the exposure, while independent analysis from Raxis provides additional technical context on the forced-browsing vector. The associated EPSS score rose materially from a low baseline to a peak of 0.0663 on 2025-12-11 before receding, indicating increased exploitation interest well after initial disclosure.

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.
Forcing a decision on every access request, including direct ones, reduces the exploitability of forced browsing by ensuring no unchecked access paths.
Forces all accesses through the reference monitor, preventing direct or forced requests that bypass checks.
Enforcing access for all logical requests prevents unauthorized direct access to protected resources.
Displaying the notification before further access on public systems prevents direct resource requests from bypassing the required system use terms and consent.
Decoy endpoints catch forced browsing and direct requests, deflecting attackers from legitimate resources while enabling analysis.
Blocks unauthorized direct requests or forced browsing by denying input access to non-authorized actors.
