What is CVE-2025-34179?

NetSupport Manager versions earlier than 14.12.0001 have a vulnerability in the Connectivity Server/Gateway that allows unauthenticated SQL injection via unsanitized request handling. This flaw enables remote attackers to manipulate the LinkName/URI value, leading to control over the FileName field used by the server. Consequently, attackers can exploit this to read unauthorized file data from the server's disk, resulting in arbitrary local file disclosure.
