Summary
CVE-2024-12342 is a high-severity Improper Resource Shutdown or Release (CWE-404) vulnerability in Tp Link (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, ranked in the top 5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.
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-2024-12342 is a denial-of-service vulnerability in the TP-Link VN020 F3v(T) TT_V6.2.1021 router firmware. It resides in the Incomplete SOAP Request Handler component, specifically the file /control/WANIPConnection, where improper handling of incomplete SOAP requests can be abused to disrupt service availability. The issue is tracked under CWE-404 and carries a CVSS 4.0 score of 7.1 reflecting high impact on availability when exploited over an adjacent network.
An attacker on the local network can send crafted incomplete SOAP requests to the affected endpoint without authentication, causing the device to become unavailable. The exploit has been publicly disclosed and is accompanied by a proof-of-concept, enabling any local adversary to trigger the condition and produce a denial-of-service condition against the router.
No vendor advisory or patch information is supplied in the available references, which include only a public exploit repository, VulDB entries, and the TP-Link homepage. The associated EPSS score has remained flat at 0.1221 with no material increase since disclosure.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect resource releases after code is written.
Engineering principles can require explicit resource acquisition/release patterns that stop improper shutdown from being introduced.
Priority-based resource allocation limits the blast radius when released resources are not returned to the pool.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
documenting procedures for secure operation, error handling, restart/recovery and resource management (including references to 8.13/8.18) is a governance and dependency control that does not itself stop exploitation of a resource-shutdown flaw; any prevention would require other controls (e.g. code changes or runtime enforcement) configured to act on it
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-404, a class-level weakness, and none of its children carries one either.
