Descripción técnica

FreeRDP before 3.32.2 contains an improper certificate validation vulnerability in tls_verify_certificate() that accepts Common Name fallback despite non-matching SAN entries and matches IP literals against DNS strings. Man-in-the-middle attackers holding a certificate from a client-trusted CA can bypass server identity checks to intercept RDP sessions, including keystrokes, clipboard, and screen content.

———Improper Certificate Validation (CWE-295) in the operating system certificate bundle shipped in the Docker images of APM Server; Auditbeat, Filebeat, Heartbeat, Metricbeat and Packetbeat; Elastic Agent, including Fleet Server and Cloudbeat; Logstash, for TLS connections that use the operating system certificate bundle; Elastic connectors; Universal Profiling (host agent, collector and symbolizer); and Elastic Maps Server. This certificate bundle, a dependency of these products (Dependency on Vulnerable Third-Party Component, CWE-1395), could allow an attacker to intercept or modify TLS-protected traffic via Signature Spoofing by Key Theft (CAPEC-474). The certificate bundle includes root certificate authorities that signed eight eMudhra intermediate certificate authorities whose private keys are compromised. Anyone with these keys can issue a certificate for any host name that these products accept as trusted. Exploitation requires an attacker in a network position between the product and the remote party, who presents a certificate issued with one of the compromised keys.2h

———bbs-go through 4.4.6 contains an improper certificate validation vulnerability that allows network-positioned attackers to intercept SMTP traffic because sendEmail() sets InsecureSkipVerify to true. Attackers can present any certificate to capture SMTP PLAIN auth credentials and read or modify outgoing password-reset and verification emails.3h

——0OpenAlgo 1.0.0.29 before 2.0.3.1 contains an improper certificate validation vulnerability in utils/email_utils.py and utils/email_debug.py that disables TLS hostname and certificate checks for STARTTLS and SMTPS. Network-positioned attackers can present a forged certificate to intercept SMTP credentials and all later mail, including password-reset links.1d

——0A flaw was found in konflux-ci. This vulnerability allows privilege escalation when the user interface proxy automatically disables Transport Layer Security (TLS) certificate verification for connections to internal backend services in environments lacking a default service certificate authority. Because the proxy attaches a cluster-scoped authentication token with user impersonation rights to these requests, an adjacent network attacker capable of intercepting traffic can capture the credentials to gain full administrative control of the cluster.22h
