CVE-2025-34181: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in NetSupport Software Manager
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.
AI Analysis
Technical Summary
CVE-2025-34181 is a path traversal vulnerability (CWE-22) in NetSupport Manager's Connectivity Server/Gateway PUTFILE request handler. It allows an attacker possessing a valid Gateway Key to perform arbitrary file writes by including directory traversal sequences in the filename parameter. This can enable placing attacker-controlled DLLs or executables in privileged directories, resulting in remote code execution with the privileges of the connectivity service. The vulnerability affects versions prior to 14.12.0001. The CVSS 4.0 base score is 8.7, indicating high severity. There is no vendor advisory or patch link currently available, and the product is not a cloud service.
Potential Impact
Successful exploitation allows an attacker with valid Gateway Key access to write arbitrary files to any location on the server, including privileged directories. This can lead to remote code execution under the NetSupport Manager connectivity service context, potentially compromising the entire system running the service. The high CVSS score reflects the significant risk posed by this vulnerability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the Gateway Key to trusted users only and monitor for any unusual file write activity related to the Connectivity Server/Gateway. Avoid exposing the Connectivity Server/Gateway interface to untrusted networks.
