CVE-2020-15589 — Zohocorp Manageengine Desktop Central security vulnerability
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.

Command, code, expression, and template injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
- Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
- Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.
Remediate safely
- Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
- Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
- Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
