Zoho ManageEngine OpManager before 12.3 Build 123196 does not require authentication for /oputilsServlet requests, as demonstrated by a /oputilsServlet?action=getAPIKey request that can be leveraged against Firewall Analyzer to add an admin user via /api/json/v2/admin/addUser or conduct a SQL Injection attack via the /api/json/device/setManaged name parameter.
Incorrect Access Control in FailOverHelperServlet in Zoho ManageEngine Netflow Analyzer before build 123137, Network Configuration Manager before build 123128, OpManager before build 123148, OpUtils before build 123161, and Firewall Analyzer before build 123147 allows attackers to read certain files on the web server without login by sending a specially crafted request to the server with the operation=copyfile&fileName= substring.
A reflected Cross-site scripting (XSS) vulnerability in Zoho ManageEngine Netflow Analyzer before build 123137, Network Configuration Manager before build 123128, OpManager before build 123148, OpUtils before build 123161, and Firewall Analyzer before build 123147 allows remote attackers to inject arbitrary web script or HTML via the parameter 'operation' to /servlet/com.adventnet.me.opmanager.servlet.FailOverHelperServlet.
Zoho ManageEngine OpManager 11 through 12.2 uses a custom encryption algorithm to protect the credential used to access the monitored devices. The implemented algorithm doesn't use a per-system key or even a salt; therefore, it's possible to create a universal decryptor.
PGSQL:SubmitQuery.do in ZOHO ManageEngine OpManager 11.6, 11.5, and earlier allows remote administrators to bypass SQL query restrictions via a comment in the query to api/json/admin/SubmitQuery, as demonstrated by "INSERT/**/INTO."
ZOHO ManageEngine OpManager 11.5 build 11600 and earlier uses a hardcoded password of "plugin" for the IntegrationUser account, which allows remote authenticated users to obtain administrator access by leveraging knowledge of this password.
Multiple SQL injection vulnerabilities in the FailOverHelperServlet (aka FailServlet) servlet in ZOHO ManageEngine OpManager 8 through 11.5 build 11400 and IT360 10.5 and earlier allow remote attackers and remote authenticated users to execute arbitrary SQL commands via the (1) customerName or (2) serverRole parameter in a standbyUpdateInCentral operation to servlet/com.adventnet.me.opmanager.servlet.FailOverHelperServlet.
