CVE-2023-42797 — Siemens Sicam A8000 Cp-8050 Firmware security vulnerability

High CVSS 7.2

A vulnerability has been identified in CP-8031 MASTER MODULE (All versions < CPCI85 V05.20), CP-8050 MASTER MODULE (All versions < CPCI85 V05.20). The network configuration service of affected devices contains a flaw in the conversion of ipv4 addresses that could lead to an uninitialized variable being used in succeeding validation steps. By uploading specially crafted network configuration, an authenticated remote attacker could be able to inject commands that are executed on the device with root privileges during device startup.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
