CVE-2021-44525
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedZoho ManageEngine PAM360 before build 5303 allows attackers to modify a few aspects of application state because of a filter bypass in which authentication is not required.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceZoho ManageEngine PAM360 before build 5303 contains a filter bypass vulnerability that allows unauthenticated attackers to modify certain application state due to missing authentication checks in specific code paths.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm PAM360 installationLocate the ManageEngine PAM360 installation directory, typically found under the ManageEngine or Zoho installation folder, or check for the PAM360 service running on your Windows or Linux server.Affected if PAM360 is installed on the system
-
Check installed build numberAccess the PAM360 administrative interface and navigate to the About or Version section to retrieve the exact build number, or check the product release information file in the installation directory.Affected if The build number is 5302 or lower, or matches versions 4.0, 4.1, 4.5, 5.0, 5.1, 5.2, or 5.3
-
Verify authentication configurationReview the authentication configuration settings in the PAM360 admin console to confirm whether the application enforces authentication on all endpoints, particularly any API or state-modifying endpoints.Affected if Authentication enforcement is missing or misconfigured for certain code paths
The environment is affected if ManageEngine PAM360 is installed with a build version prior to 5303 (versions 4.0 through 5.3), as these contain the authentication bypass vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade PAM360 to build 5303 or later to remediate the authentication bypass vulnerability and restore proper access controls.
Build 5303 or later
- 1. Identify the current build version of ManageEngine PAM360 installation
- 2. Download the latest build of PAM360 from the official ManageEngine download portal or contact vendor support
- 3. Before upgrading, take a complete backup of the PAM360 database and configuration files
- 4. Stop the PAM360 service
- 5. Install/apply the updated build (5303 or later)
- 6. Start the PAM360 service
- 7. Verify the authentication bypass vulnerability is resolved by attempting unauthorized access to the previously vulnerable endpoints
- 8. Confirm normal administrative functions work correctly
