CVE-2016-1159
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 · uneditedIn ZOHO Password Manager Pro (PMP) 8.3.0 (Build 8303) and 8.4.0 (Build 8400,8401,8402), underprivileged users can obtain sensitive information (entry password history) via a vulnerable hidden service.
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 Password Manager Pro versions 8.3.0 and 8.4.0 contain a vulnerability in a hidden service that allows underprivileged users to bypass authorization controls and access sensitive password history data that should be restricted to higher-privileged users. This is an information disclosure vulnerability stemming from improper access control on the password history feature.

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.
-
Identify the installed version of Password Manager ProAccess the admin console or check the product installation directory for the version information. Typically found in the 'About' section of the admin interface or in the product's version file in the installation folder.Affected if The installed version is exactly 8.3.0 or 8.4.0
-
Locate the password history configurationAccess the admin console and navigate to the password policy or password settings section where password history storage is configured.Affected if Password history feature is enabled and storing historical passwords for user accounts
-
Identify the hidden service endpointReview web service configuration files and application logs for any undocumented or hidden API endpoints related to password history retrieval. Check for URLs containing 'history' or 'pwdhistory' patterns.Affected if A hidden or undocumented service endpoint exists that provides access to password history data
-
Verify authorization controls on password history accessTest access to password history data using a low-privilege user account that should not have access to other users' password history. Attempt to retrieve historical passwords through the identified endpoints.Affected if Low-privilege users can successfully access password history data belonging to higher-privileged users
You are affected if you are running version 8.3.0 or 8.4.0 of Zoho Password Manager Pro with password history enabled, and low-privilege users can access password history data through the hidden service endpoint.

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.
From vendor dataUpdate ZOHO Password Manager Pro to a patched version that addresses this authorization bypass. Review password history for any exposed credentials and rotate as necessary.
