Summary
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.
Risk Assessment
Exposure of the Gateway Key could allow an attacker to gain full control over systems managed by NetSupport Manager, posing a serious threat to confidentiality and integrity.
Recommendation
Update NetSupport Manager to version 14.12.0001 or later. Restrict access to client configuration files.
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-2025-34179High
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.
Original NVD description (English source)
NetSupport Manager < 14.12.0001 relies on a shared Gateway Key for authentication between Manager/Control, Client, and Connectivity Server components. The key is stored using a reversible encoding scheme. An attacker who obtains access to a deployed client configuration file can decode the stored value to recover the plaintext Gateway Key. Possession of the Gateway Key allows unauthorized access to NetSupport Manager connectivity services and enables remote control of systems managed through the same key.
