Server-Side Request Forgery in ManageEngine Desktop Central

Zoho ManageEngine ADManager Plus 6.6.5, ADSelfService Plus 5.7, and DesktopCentral 10.0.380 have Insecure Permissions, leading to Privilege Escalation from low level privileges to System.

A design issue was discovered in GetInternetRequestHandle, InternetSendRequestEx and InternetSendRequestByBitrate in the client side of Zoho ManageEngine Desktop Central 10.0.552.W and Remote Access Plus before 10.1.2119.1. By exploiting this issue, an attacker-controlled server can force the client to skip TLS certificate validation, leading to a man-in-the-middle attack against HTTPS and unauthenticated remote code execution.

Multiple Zoho ManageEngine products suffer from local privilege escalation due to improper permissions for the %SYSTEMDRIVE%\ManageEngine directory and its sub-folders. Moreover, the services associated with said products try to execute binaries such as sc.exe from the current directory upon system start. This will effectively allow non-privileged users to escalate privileges to NT AUTHORITY\SYSTEM. This affects Desktop Central 10.0.380, EventLog Analyzer 12.0.2, ServiceDesk Plus 10.0.0, SupportCenter Plus 8.1, O365 Manager Plus 4.0, Mobile Device Manager Plus 9.0.0, Patch Connect Plus 9.0.0, Vulnerability Manager Plus 9.0.0, Patch Manager Plus 9.0.0, OpManager 12.3, NetFlow Analyzer 11.0, OpUtils 11.0, Network Configuration Manager 11.0, FireWall 12.0, Key Manager Plus 5.6, Password Manager Pro 9.9, Analytics Plus 1.0, and Browser Security Plus.

The MPS Agent in Zoho ManageEngine Desktop Central MSP build MSP build 10.0.486 is vulnerable to DLL Hijacking: dcinventory.exe and dcconfig.exe try to load CSUNSAPI.dll without supplying the complete path. The issue is aggravated because this DLL is missing from the installation, thus making it possible to hijack the DLL and subsequently inject code, leading to an escalation of privilege to NT AUTHORITY\SYSTEM.

An issue was discovered in the Self Service Portal in Zoho ManageEngine Desktop Central before 10.0.282. A clickable company logo in a window running as SYSTEM can be abused to escalate privileges. In cloud, the issue is fixed in 10.0.470 agent version.
