ASE/Kalkitech ASE2000 V2 Communication Test Set 2.35 through 2.37 on Windows contains an improper certificate validation vulnerability in the IEC 60870-5-104 TLS client (Task Mode). This allows a network-positioned attacker to bypass certificate validation via a certificate with multiple simultaneous faults, enabling a Man-in-the-Middle attack on protected communications.

CVE-2026-906518.1 HIG—
———Socket Firewall (socketdev/socket-registry-firewall) in registry mode before 2.0.0 does not verify upstream TLS certificates by default. When the api_ssl_verify and upstream_ssl_verify configuration keys are omitted from socket.yml, the generated configuration sets SOCKET_API_SSL_VERIFY='false' and UPSTREAM_SSL_VERIFY='false', and the OpenResty/Lua HTTP client used for outbound requests accepts any certificate, including self-signed and otherwise untrusted certificates, without validating the chain. An attacker positioned to intercept traffic between Socket Firewall and the Socket API or an upstream package registry can present a crafted certificate and modify responses in transit, including substituting malicious package content or altering the allow/block decisions the firewall enforces. Setting api_ssl_verify: true and upstream_ssl_verify: true enables verification; however, in versions before 1.1.334, the generated nginx configuration did not emit lua_ssl_trusted_certificate, and thus verification could not be used successfully without manually patching the generated configuration. Version 2.0.0 changes the default for both settings to true.3hCVE-2026-90452——
——0Requests from the reverse proxy to the identity-provider service for token discovery, introspection, and credential exchange do not verify the identity provider's server certificate. An attacker positioned on the network path between the proxy and the identity provider could impersonate the identity provider and issue forged authentication tokens accepted by the deployment.1dCVE-2026-878726.8 MED0.5%
——0A flaw was found in the OCAPI modules (ocapi_command, ocapi_info) of the
community.general Ansible collection. The shared OCAPI request helper disables
TLS certificate validation on every request and the modules expose no parameter
to re-enable it, while sending HTTP Basic-Auth credentials to an https endpoint.
An attacker positioned on the network path between the Ansible controller and the
OCAPI-managed storage/enclosure device can present any certificate, intercept the
session, capture the credentials, and tamper with responses.3dCVE-2026-797363.7 LOW2.4%
