CVE-2023-52236 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in RUGGEDCOM i800 from Siemens, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected RUGGEDCOM i800 versions: all versions. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.2% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update RUGGEDCOM RMC8388 V5.X to V5.10.0 or a later version.
  2. Update RUGGEDCOM RS416Pv2 V5.X to V5.10.0 or a later version.
  3. Update RUGGEDCOM RS416v2 V5.X to V5.10.0 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Use of a Broken or Risky Cryptographic Algorithm

The product uses a broken or risky cryptographic algorithm or protocol.

How developers prevent this class of flaw

  • Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms. With hardware, design the product at the Intellectual Property (IP) level so that one cryptographic algorithm can be replaced with another in the next generation of the hardware product.
  • Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Industry-standard implementations will save development time and may be more likely to avoid errors that can occur during implementation of cryptographic algorithms. Consider the ESAPI Encryption feature.
