Executive Summary

Hirschmann EagleSDV contains a denial-of-service vulnerability that causes the device to crash during session establishment when using TLS 1.0 or TLS 1.1.

Attackers can exploit this vulnerability by initiating TLS connections with these older protocol versions, which disrupts the device's service availability.

Impact Analysis

This vulnerability can impact you by causing denial of service on the Hirschmann EagleSDV device.

An attacker can trigger a crash by initiating TLS connections using TLS 1.0 or TLS 1.1, which disrupts the availability of the device and any services relying on it.

Mitigation Strategies

To mitigate this vulnerability, avoid using TLS 1.0 or TLS 1.1 when establishing sessions with Hirschmann EagleSDV devices prior to version 05.4.02, as these protocol versions can trigger a denial-of-service crash.

Upgrading the device firmware to version 05.4.02 or later will resolve the issue.
