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 classified as cross-site scripting (CWE-79) affects PHP Jabbers Shuttle Booking Software version 1.0. The issue exists in an unspecified portion of the file /index.php, where unsanitized input manipulation enables reflected or stored script injection. It carries a CVSS 3.1 base score of 4.3 and was publicly disclosed on 2023-08-03 after the vendor did not respond to early notification.

An unauthenticated remote attacker can trigger the flaw by supplying crafted input that is rendered in a victim's browser when the affected page is loaded, requiring user interaction such as clicking a malicious link. Successful exploitation permits limited alteration of page content or session behavior without direct impact on confidentiality or availability.

Public references, including Packet Storm and Vuldb entries, reproduce proof-of-concept requests but contain no vendor-supplied patches or configuration guidance. The associated EPSS score reached a peak of 0.1710 with a current value of 0.1513, indicating modest post-disclosure interest without evidence of widespread exploitation.

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).
