CVE-2026-56454: HCL DFXAnalytics use of deprecated TLS 1.0 and 1.1 protocols

CVE-2026-56454 · Severity: medium · CVSS 5.9 · Published 2026-07-16

Technologies: HCL Software DFXAnalytics. Vendors: HCL Software.

Executive brief

HCL DFXAnalytics is an analytics platform that uses outdated security protocols (TLS 1.0 and 1.1) to protect data in transit. These legacy protocols have known weaknesses that could allow a sophisticated attacker to intercept and read sensitive information as it travels across the network. Organizations using this software should update to versions that support modern encryption standards like TLS 1.2 or 1.3 to ensure data privacy.

Technical details

HCL DFXAnalytics versions 3.0 and below are vulnerable to cryptographic design flaws (CWE-327) due to the continued support of deprecated TLS 1.0 and TLS 1.1 protocols. An unauthenticated remote attacker can exploit these legacy protocols via man-in-the-middle (MITM) attacks to intercept and decrypt encrypted traffic. While the attack complexity is high due to the requirements for intercepting network traffic and exploiting specific cryptographic weaknesses, the impact on confidentiality is significant. Remediation requires disabling TLS 1.0/1.1 and enforcing the use of TLS 1.2 or TLS 1.3.
