Unauthenticated code execution via malformed ECDSA signatures
Published Sep 25, 2024 · Updated Sep 26, 2024
Improper authentication in affected TheGreenBow VPN Clients allows remote attackers to establish IKEv2 tunnels with malformed ECDSA signatures. During IKEv2 authentication, the signature-validation path accepts a malformed ECDSA signature as valid and completes tunnel establishment. The attacker must supply the malicious gateway authentication exchange; the CVE record reports arbitrary code execution as the resulting impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
