CVE-2024-14033: CWE-400: Uncontrolled Resource Consumption in Belden Hirschmann EagleSDV
Hirschmann EagleSDV firmware prior to 05.4.02 contains a denial-of-service vulnerability in TLS session establishment. Attackers can crash the device during TLS handshake by exploiting protocol downgrades to TLS 1.0 or TLS 1.1, interrupting service availability.
AI Analysis
Technical Summary
The Hirschmann EagleSDV firmware before version 05.4.02 contains a vulnerability classified as CWE-400 (Uncontrolled Resource Consumption) that can be triggered during the TLS handshake process. Attackers can force the device to downgrade the TLS protocol to versions 1.0 or 1.1, which leads to a denial-of-service condition by crashing the device and disrupting its availability. This vulnerability does not impact confidentiality or integrity but causes high availability impact. The vulnerability is remotely exploitable without authentication and requires no user interaction.
Potential Impact
Successful exploitation causes a denial-of-service condition by crashing the affected Hirschmann EagleSDV device during TLS handshake, resulting in service interruption. There is no impact on confidentiality or integrity. The vulnerability affects network availability and could disrupt operations relying on the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or workaround information is provided, users should monitor Belden's advisories for firmware updates addressing this issue. Until a fix is available, consider restricting network access to the device to trusted sources to reduce exposure to potential exploitation attempts.
