Sensitive data disclosure via cleartext TCP traffic
Published May 22, 2026 · Updated May 22, 2026
Cleartext transmission in STER before 9.5 allows man-in-the-middle attackers to read sensitive data from TCP network traffic. The application sends passwords, personal data, and authentication tokens over TCP without transport encryption, exposing their plaintext to an on-path interceptor. Exploitation requires network-path access to STER traffic, and the reported consequence is disclosure rather than data modification or service interruption.

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.
