CVE-2023-44319
CVE-2023-44319
In short
These industrial network devices use weak cryptographic algorithms to protect data transmission, making it possible for attackers to decrypt or intercept sensitive communications. This affects routers and gateways used in critical infrastructure, potentially allowing unauthorized access to industrial systems.
Technical detail
CWE-328 identifies the use of insufficiently strong cryptographic algorithms in affected Siemens RUGGEDCOM and SCALANCE devices (firmware versions before V8.0 and V3.0.0). An attacker with network access can intercept encrypted communications and potentially recover plaintext data due to weak cipher implementations; this requires proximity to network traffic but does not require authentication.

This could allow an authenticated attacker with administrative privileges or an attacker that tricks a legitimate administrator to upload a modified configuration file to change the configuration of an affected device.
