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.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H","score":8.4},"cvss_v3":null,"cwes":["CWE-257"],"references":["https://kb.netsupportsoftware.com/knowledge-base/updating-and-securing-netsupport-manager/","https://ret2.me/post/2025-12-04-exploiting-netsupport-gateway/","https://www.vulncheck.com/advisories/netsupport-manager-gateway-key-reversible-encoding-credential-recovery"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-34180","score":0.00181,"percentile":0.07632,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
