Summary
MicroStation applications may be affected by a certificate validation vulnerability in the libcurl library. The vulnerability occurs when MicroStation uses libcurl for HTTPS transfers with QUIC/HTTP/3 connections and wolfSSL backend. wolfSSL is an SSL implementation targeting embedded systems. It is unlikely that MicroStation operating in a corporate environment would encounter this situation.

Details
MicroStation uses libcurl versions 8.5.0 to 8.14.0 which are affected by improper certificate validation (CWE-295) when using QUIC for HTTP/3 connections with wolfSSL backend. The certificate pinning check that should verify the server’s public key is omitted in this specific configuration within libcurl, potentially allowing MicroStation to unwittingly connect to impostor servers during network operations. While libcurl documentation indicates the option works with wolfSSL, it fails to specify that it does not function properly for QUIC and HTTP/3 connections.

Affected Versions

Recommended Mitigations
Bentley recommends updating to the latest product version. Best practice is to ensure communications are made over trusted networks and verify server certificates.
