Summary
NetSupport Manager < 14.12.0001 contains an unauthenticated SQL injection vulnerability in its Connectivity Server/Gateway HTTPS request handling. The server evaluates request URIs using an unsanitized SQLite query against the FileLinks table in gateway.db. By injecting SQL through the LinkName/URI value, a remote attacker can control the FileName field used by the server to read and return files from disk, resulting in arbitrary local file disclosure.
Risk Assessment
The risk includes the possibility of remote reading of arbitrary files from the system, including sensitive data, without authentication, which may lead to serious confidentiality breaches.
Recommendation
It is recommended to immediately update NetSupport Manager to version 14.12.0001 or later and to restrict access to the Connectivity Server/Gateway to trusted networks only.
Other vulnerabilities in NetSupport Manager
See all- CVE-2025-34181High
NetSupport Manager < 14.12.0001 contains an arbitrary file write vulnerability in its Connectivity Server/Gateway PUTFILE request handler. An attacker with a valid Gateway Key can supply a crafted filename containing directory traversal sequences to write files to arbitrary locations on the server. This can be leveraged to place attacker-controlled DLLs or executables in privileged paths and achieve remote code execution in the context of the NetSupport Manager connectivity service.
- CVE-2025-34180High
NetSupport Manager before 14.12.0001 relies on a shared Gateway Key for authentication. The key is stored using a reversible encoding scheme, allowing an attacker with access to a client configuration file to recover the key and gain unauthorized access to connectivity services and remote control of systems.
