An improper access control vulnerability exists in the multi-factor authentication (MFA) functionality of ManageEngine SharePoint Manager Plus (SPMP). A low-privileged authenticated user can bypass authorization checks to read and modify MFA configuration settings, enable or disable MFA for the application, enumerate MFA-enrolled users, and delete MFA-enrolled accounts. Successful exploitation could allow an attacker to weaken authentication protections or cause a denial of service by configuring invalid MFA settings, potentially locking legitimate users out of the application. This vulnerability was fixed in build 4507. The reproduction explicitly uses build 4506.

A stored cross-site scripting (XSS) vulnerability exists in the chart feature of SharePoint Manager Plus (SPMP) due to improper sanitization and HTML encoding of user-controlled data. An attacker can inject malicious HTML or JavaScript into attributes used to generate charts, including users' full names, site names, or group names. The injected content is stored and subsequently executed in the context of other users' browsers when the affected charts are rendered. This vulnerability was fixed in client application build 4508.

An information disclosure vulnerability exists in multiple ManageEngine products that can result in encryption keys being exposed. A low-privileged OS user with access to the host where an affected ManageEngine product is installed can view and use the exposed key to decrypt product database passwords. This allows the user to access the ManageEngine product database.
