CVE-2026-108361 Details
Description
Privasys Remote Attestation TLS Clients provides multi-language utilities for verifying attested TLS connections. Before 0.9.1, an attacker with local access could modify workload code, data, and configuration at any time after successful connection establishment. Once Evidence was successfully appraised and the connection was established, there was a window of vulnerability from the establishment of the connection to the termination of the connection where an attacker could modify the state of the workload and platform at runtime on the TLS endpoint acting as the Attester. This vulnerability was possible because Privasys/ra-tls-clients performed attestation only once in the lifetime of the connection (at connection establishment time), and the verifying peer continued to believe that the state was the same as in the initial Evidence throughout, whereas it could be stale at some point in time. This vulnerability is fixed in 0.9.1.
A vulnerability exists in Privasys Remote Attestation TLS Clients in versions prior to 0.9.1, allowing an attacker with local access to modify workload code, data, and configuration after a TLS connection has been established. This issue arises because the client only performs attestation once per connection, creating a time-of-check to time-of-use (TOCTOU) vulnerability. Once the connection is established, there is a window where an attacker can alter the workload state on the TLS endpoint acting as the Attester. The vulnerability is particularly concerning for long-lived connections, as the verifying peer may operate under stale assumptions about the workload state.
Users are advised to upgrade to Privasys Remote Attestation TLS Clients version 0.9.1 or later. For Python and .NET clients, version 0.10.0 or later is recommended.
