CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-28347 is a critical-severity Cross-site Scripting (CWE-79) vulnerability in Faronics Insight. Its CVSS base score is 9.6 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 14% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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-2023-28347 affects Faronics Insight version 10.0.19045 on Windows. The flaw permits an attacker to build a proof-of-concept script that emulates a Student Console, thereby exploiting cross-site scripting weaknesses (CWE-79) present in the Teacher Console application and enabling unauthenticated remote code execution.
An unauthenticated attacker can leverage the crafted script to obtain code execution as NT AUTHORITY/SYSTEM on the Teacher Console and every connected Student Console. The attack requires no user interaction and completes in a zero-click fashion over the network, corresponding to the CVSS 9.6 rating.
Public technical advisories published by NCC Group detail the multiple vulnerabilities discovered in Faronics Insight and provide the research findings at the listed URLs; organizations should consult these resources for patch availability and recommended defensive steps.
EPSS scores have remained low and stable near 0.09 with no material increase after 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.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
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.
A.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
