Summary

CVE-2023-6319 is a critical-severity OS Command Injection (CWE-78) vulnerability in Lg Webos. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — 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.

A command injection vulnerability exists in the getAudioMetadata method of the com.webos.service.attachedstoragemanager service on LG webOS versions 4 through 7. The flaw, tracked as CVE-2023-6319 and assigned CWE-78, permits specially crafted requests to execute arbitrary commands as the root user. Affected devices include specific firmware builds on models such as the LG43UM7000PLA, OLED55CXPUA, OLED48C1PUB, and OLED55A23LA, with a CVSS 3.1 score of 9.1 reflecting network-accessible, high-impact exploitation.

An authenticated attacker can send a sequence of malicious requests to the service and obtain root-level command execution on the television. This grants full control over the device, including the ability to read, modify, or delete data and potentially pivot within the local network due to the changed scope in the CVSS vector.

LG has published security bulletins that address the issue and provide update information for impacted webOS platforms; Bitdefender has also released a detailed advisory describing the vulnerabilities. The EPSS score has remained flat at 0.1079 with no material increase observed since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

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).
