Description
Privasys Remote Attestation TLS Clients provides multi-language utilities for verifying attested TLS connections. Prior to 0.11.0, TEE attestation evidence in Privasys attested TLS is accepted without requiring an explicitly authorized platform identity. When a network attacker can forge evidence or extract attestation secrets from a compromised unrevoked platform, the verifier accepts valid measurements from a different unrevoked TEE platform as though they came from the intended Attester. The attacker can impersonate the attested TLS endpoint. This issue is fixed in version 0.11.0.

AI Analysis

Impact

The vulnerability allows a network attacker to forge or steal attestation evidence from a compromised unrevoked TEE platform. Because the verifier does not require an explicitly authorized platform identity, it accepts evidence that belongs to any unrevoked TEE as if it originated from the intended attester. The attacker can impersonate the attested TLS endpoint, potentially leading to man‑in‑the‑middle attacks and unauthorized data access. This flaw represents a serious authentication bypass, classified as CWE‑346.

Affected Systems

The affected product is Privasys ra‑tls‑clients. All releases prior to version 0.11.0 are vulnerable; the fix was introduced in release v0.11.0. Users of any earlier version should consider their installations at risk until the update is applied.

Risk and Exploitability

The CVSS score of 9.1 highlights the high severity of this flaw. EPSS data is not available, and the vulnerability is not listed in CISA KEV. The attack vector is inferred to involve a remote attacker who can forge or extract attestation secrets over a network and supply them to the TLS verifier. Once the evidence is accepted, the attacker can fully impersonate the TLS endpoint, gaining control over encrypted communications.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to Privasys ra‑tls‑clients v0.11.0 or newer to apply the fix.
  • Reconfigure the TLS client to require explicit verification of the attester’s platform identity before accepting evidence.
  • Audit all deployed TEE platforms for unauthorized or compromised devices and revoke any that are detected.
