CVE-2025-14823Network attack vector

Unauthenticated encrypted configuration disclosure via client responses

Published Dec 18, 2025 · Updated Dec 18, 2025

Sensitive data exposure in ScreenConnect Certificate Signing Extension before 1.0.12 allows remote attackers to read encrypted configuration values. The extension sends encrypted Azure Key Vault-related configuration through an unnamed client-facing endpoint instead of keeping it exclusively on the server. Exposure requires the extension and affected configuration conditions; disclosed values remain encrypted, with no reported plaintext access or modification.
