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 vulnerability rated as problematic has been identified in PHP Jabbers Night Club Booking Software version 1.0. The issue resides in an unspecified processing function within the file /index.php, where manipulation of the index argument enables cross-site scripting. This flaw is tracked under CVE-2023-4114 and CWE-79, with a CVSS v3.1 base score of 4.3 reflecting network attack vector, low complexity, and required user interaction.

An unauthenticated remote attacker can exploit the weakness by supplying crafted input to the affected parameter, causing arbitrary script execution in the context of a victim's browser session. Successful exploitation could allow theft of session tokens, redirection to malicious sites, or other client-side actions without affecting server confidentiality or availability.

The vendor was contacted prior to disclosure but provided no response, and no official patches or mitigation guidance appear in the available references. Public exploit details have been posted to Packet Storm, while EPSS scores remain low with only minor fluctuation between the current value of 0.0676 and a peak of 0.0783.

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.

CA-8 Penetration Testing
addresses: CWE-79

Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.

SI-10 Information Input Validation
addresses: CWE-79

Validates web inputs to reject script-related content that could produce XSS.

SI-15 Information Output Filtering
addresses: CWE-79

Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.

PR.PS-06 mostly match
blocks

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).

PR.PS-02 partial match
blocks

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).
