Summary

CVE-2023-22598 is a high-severity OS Command Injection (CWE-78) vulnerability in Inhandnetworks Inrouter302 Firmware. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 24% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

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

InHand Networks InRouter 302 prior to version IR302 V3.5.56 and InRouter 615 prior to version InRouter6XX-S-V2.3.0.r5542 are affected by an OS command injection vulnerability tracked as CWE-78. The flaw resides in the handling of configuration update files submitted through the local web interface or associated cloud management account, allowing improper neutralization of special elements used in operating system commands.

An attacker with privileged access to either the web interface or the cloud account can upload a specially crafted configuration file that results in remote code execution with root privileges on the affected router. The CVSS 3.1 score of 7.2 reflects the requirement for high privileges and the high impact on confidentiality, integrity, and availability.

CISA has published advisory ICSA-23-012-03 detailing the issue. The EPSS score rose materially from a low baseline to a peak of 0.2350 on 2025-01-22 before receding to the current value of 0.0153, indicating that exploitation interest increased well after initial disclosure.

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
blocks

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
blocks

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).
