CVE-2016-1159Network attack vector

Password-history disclosure via manipulated request URL

Published Mar 9, 2020 · Updated Aug 5, 2024

Broken access control in Zoho Password Manager Pro builds 8303 and 8400 through 8402 allows remote authenticated users to read password history. The password-history service accepts a manipulated request URL and returns old passwords for accounts not shared with the requesting user. Authenticated password-user access is sufficient, exposing historic credentials from otherwise unshared vault entries.
