In Zoho ManageEngine Application Manager 13.1 Build 13100, the administrative user has the ability to upload files/binaries that can be executed upon the occurrence of an alarm. An attacker can abuse this functionality by uploading a malicious script that can be executed on the remote system.

In Zoho ManageEngine Application Manager 13.1 Build 13100, an authenticated user, with administrative privileges, has the ability to add a widget on any dashboard. This widget can be a "Utility Widget" with a "Custom HTML or Text" field. Once this widget is created, it will be loaded on the dashboard where it was added. An attacker can abuse this functionality by creating a "Utility Widget" that contains malicious JavaScript code, aka XSS.

Zoho ManageEngine Applications Manager 12 through 14 allows FaultTemplateOptions.jsp resourceid SQL injection. Subsequently, an unauthenticated user can gain the authority of SYSTEM on the server by uploading a malicious file via the "Execute Program Action(s)" feature.

An issue was discovered in Zoho ManageEngine Applications Manager 11.0 through 14.0. An unauthenticated user can gain the authority of SYSTEM on the server due to a Popup_SLA.jsp sid SQL injection vulnerability. For example, the attacker can subsequently write arbitrary text to a .vbs file.

A serialization vulnerability in Zoho ManageEngine Applications Manager before build 13740 allows for remote code execution on Windows via a payload on an SMB share.

A reflected Cross-site scripting (XSS) vulnerability in Zoho ManageEngine Applications Manager 13 before build 13820 allows remote attackers to inject arbitrary web script or HTML via the /deleteMO.do method parameter.

A SQL Injection vulnerability exists in the Zoho ManageEngine Applications Manager 13 before build 13820 via the resids parameter in a /editDisplaynames.do?method=editDisplaynames GET request.

ManageEngine Applications Manager 12 and 13 before build 13690 allows an authenticated user, who is able to access /register.do page (most likely limited to administrator), to browse the filesystem and read the system files, including Applications Manager configuration, stored private keys, etc. By default Application Manager is running with administrative privileges, therefore it is possible to access every directory on the underlying operating system.

ManageEngine Applications Manager 12 and 13 before build 13200, allows unserialization of unsafe Java objects. The vulnerability can be exploited by remote user without authentication and it allows to execute remote code compromising the application as well as the operating system. As Application Manager's RMI registry is running with privileges of system administrator, by exploiting this vulnerability an attacker gains highest privileges on the underlying operating system.

In ManageEngine Applications Manager 12 and 13 before build 13200, an authenticated user is able to alter all of their own properties, including own group, i.e. changing their group to one with higher privileges like "ADMIN". A user is also able to change properties of another user, e.g. change another user's password.
