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.

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.

ManageEngine Applications Manager versions 12 and 13 before build 13200 suffer from remote SQL injection vulnerabilities. An unauthenticated attacker is able to access the URL /servlet/MenuHandlerServlet, which is vulnerable to SQL injection. The attacker could extract users' password hashes, which are MD5 hashes without salt, and, depending on the database type and its configuration, could also execute operating system commands using SQL queries.

An issue was discovered in Zoho ManageEngine OpManager through 12.4x. There is a SQL Injection vulnerability in jsp/NewThresholdConfiguration.jsp via the resourceid parameter. Therefore, a low-authority user can gain the authority of SYSTEM on the server. One can consequently upload a malicious file using the "Execute Program Action(s)" feature.

An issue was discovered in Zoho ManageEngine Application Manager through 14.2. There is a SQL Injection vulnerability in jsp/NewThresholdConfiguration.jsp via the resourceid parameter. Therefore, a low-authority user can gain the authority of SYSTEM on the server. One can consequently upload a malicious file using the "Execute Program Action(s)" feature.

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.

ManageEngine Applications Manager versions 12 and 13 before build 13200 suffer from a Reflected Cross-Site Scripting vulnerability. Applications Manager is prone to a Cross-Site Scripting vulnerability in parameter LIMIT, in URL path /DiagAlertAction.do?REQTYPE=AJAX&LIMIT=1233. The URL is also available without authentication.
