Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 7% 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.

A cross-site scripting vulnerability exists in mooSocial mooDating version 1.2 within the URL handler component handling the /users path. The issue, tracked as CVE-2023-3847 and assigned CWE-79, arises from improper input sanitization that permits script injection through manipulated parameters. It received a CVSS 3.1 score of 3.5, reflecting network attack vector, low complexity, and required user interaction.

An authenticated attacker with low privileges can supply a crafted URL that, when visited by another user, executes arbitrary JavaScript in the victim's browser context. The attack is fully remote and results in limited integrity impact without affecting confidentiality or availability. No special conditions beyond a logged-in session and victim interaction are required.

Public references on VulDB and Packet Storm document the flaw and include proof-of-concept material, but the vendor could not be reached via its published contact address and no official patch or mitigation guidance has been issued. The associated EPSS score reached a modest peak of 0.1132 before receding to its current value of 0.0992, indicating limited but observable post-disclosure interest.

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).
