CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-3479 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Hestiacp Control Panel. Its CVSS base score is 6.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 30% 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-2023-3479 is a reflected cross-site scripting vulnerability (CWE-79) affecting the Hestia Control Panel (hestiacp/hestiacp) in versions prior to 1.7.8. The flaw carries a CVSS 3.1 score of 6.1 with a network attack vector, low attack complexity, no required privileges, and required user interaction, resulting in limited impacts to confidentiality and integrity under a changed scope.
An unauthenticated remote attacker can exploit the issue by crafting a malicious URL that, when visited by an authenticated user, causes the victim's browser to execute attacker-controlled scripts within the context of the Hestia application. Successful exploitation allows limited data exposure or unauthorized actions on behalf of the targeted user but does not directly affect availability.
Public references point to commits that remediate the reflected XSS vectors; administrators should upgrade to version 1.7.8 or later to apply the fixes. The associated EPSS score reached a peak of 0.2638 before receding to its current value of 0.2352, indicating moderate but not sustained exploitation interest 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.
