A vulnerability in the showReports module of Zoho ManageEngine Applications Manager before build 14550 allows authenticated attackers to execute a SQL injection via a crafted 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.
