An issue was discovered in Zoho ManageEngine AssetExplorer 6.5. During an upgrade of the Windows agent, it does not validate the source and binary downloaded. This allows an attacker on an adjacent network to execute code with NT AUTHORITY/SYSTEM privileges on the agent machines by providing an arbitrary executable via a man-in-the-middle attack.

Weakness

The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
