RUGGEDCOM RM1224 LTE(4G) EU: Acceptance of Extraneous Untrusted Data With Trusted Data

CVE-2023-44317 is a high-severity acceptance of extraneous untrusted data with trusted data vulnerability in RUGGEDCOM RM1224 LTE(4G) EU from Siemens, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version V7.2.2 as the first without the flaw, so updating RUGGEDCOM RM1224 LTE(4G) EU to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.38% 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 RM1224 LTE(4G) EU to V7.2.2 or a later version.
  2. Update RUGGEDCOM RM1224 LTE(4G) NAM to V7.2.2 or a later version.
  3. Update SCALANCE M804PB to V7.2.2 or a later version.
  4. Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
