CVE-2026-55964
Description détaillée
Chain intermediate CA:TRUE without keyCertSign accepted as a signing CA. Intermediate CA certificates are required to have the keyCertSign key usage when a Key Usage extension is present, but chain-supplied temporary CAs (WOLFSSL_TEMP_CA) added while building a certificate path were previously exempted from this check, so an intermediate asserting CA:TRUE but lacking keyCertSign was accepted as a signing CA. The check now applies to chain-supplied temporary CAs as well; only operator-loaded root certificates (WOLFSSL_USER_CA) and self-signed roots remain exempt. Per RFC 5280 an absent Key Usage extension implies all usages, so the requirement is enforced only when the extension is actually present (extKeyUsageSet). Affects the OpenSSL-compatibility certificate-path-building path (X509_verify_cert / X509_STORE, OPENSSL_EXTRA/OPENSSL_ALL), where untrusted chain intermediates are added as temporary CAs; native (non-OpenSSL-compat) certificate verification does not create temporary CAs and is unaffected. Within those builds, the check applies unless ALLOW_INVALID_CERTSIGN is defined.

Dernières Vulnérabilités
CVE-2026-56414
A vulnerability exists in H.View IP cameras certificate-related upload interfaces allow authenticated users to store arbitrary file content to fixed, persistent filesystem locations without validating file type, structure, or size. This design omission enables the placement of unexpected or malformed data in locations intended for trusted certificate material, which could affect system integrity or behavior even after reboot.
CVE-2026-55975
A vulnerability exists in H.View IP cameras that could allow an authenticated user to supply unsanitized XML fields to the device's certificate generation interface, which are incorporated into a backend certificate creation command without proper input validation. This may allow for command execution with elevated privileges during certificate generation.
CVE-2026-33560
The DMP-5000 file service exposes authenticated arbitrary file upload functionality. There are exposed endpoints which allows authenticated users to upload files of any type without validation. No file extension filtering or content inspection is enforced which allows executable binaries and scripts to be accepted and written directly to the server.
