Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-1698 is a critical vulnerability present in multiple WAGO products. It enables unauthenticated remote attackers to create new users and modify device configuration, which can produce unintended behavior, denial of service, or full system compromise. The flaw is rated 9.8 under CVSS 3.1 and is categorized under CWE-78.

An attacker requires no credentials or user interaction and can exploit the issue over the network to achieve complete control over confidentiality, integrity, and availability on affected devices. Successful exploitation directly supports creation of administrative accounts and arbitrary configuration changes that lead to system takeover.

Public advisories addressing the vulnerability are published by VDE at https://cert.vde.com/en/advisories/VDE-2023-007/. The associated EPSS score stands at 0.9403 with no material change from its recorded peak.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
