An issue was discovered in the client side of Zoho ManageEngine Desktop Central 10.0.552.W. An attacker-controlled server can trigger an integer overflow in InternetSendRequestEx and InternetSendRequestByBitrate that leads to a heap-based buffer overflow and Remote Code Execution with SYSTEM privileges. This issue will occur only when untrusted communication is initiated with server. In cloud, Agent will always connect with trusted communication.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
