CyberRota Analysis
AI-GeneratedOpenSSL versions prior to 3.29.0 are vulnerable due to improper hostname validation in FreeRDP, allowing wildcard certificates to incorrectly authenticate multi-label subdomains. This flaw undermines TLS server authentication, potentially enabling man-in-the-middle attacks. Organizations using affected versions of FreeRDP should prioritize patching to mitigate the risk of unauthorized access and data breaches.

Original NVD Description
FreeRDP before 3.29.0 (affected versions <= 3.28.0) contains an improper certificate hostname validation vulnerability. The TLS hostname matcher (tls_match_hostname() in libfreerdp/crypto/tls.c) treats a wildcard pattern such as *.example.com as matching any hostname ending in .example.com, so it incorrectly accepts a wildcard certificate for multi-label subdomains like a.b.example.com (which OpenSSL's X509_check_host() rejects). This weakens TLS server authentication under wildcard-certificate conditions.
