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.

AU-7 Audit Record Reduction and Report Generation
addresses: CWE-779

Audit record reduction explicitly manages excessive log volumes for review and reporting while preserving original content and ordering, reducing the impact of logging excessive data.

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.

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.

DE.AE-04 mostly match
degrades

Excessive logging hinders log processing and forensic analysis, largely undermining DE.AE-04's ability to estimate impact/scope via SIEMs or tools while removing most of that outcome's efficacy.

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).

DE.AE-02 partial match
degrades

Excessive logging undermines event analysis by flooding logs with noise that hinders processing and forensic review, but does not blind or defeat the outcome the way insufficient logging would.

DE.AE-06 partial match
degrades

Excessive logging impairs processing of provided event data and log-analysis findings (one aspect of DE.AE-06) without fully defeating alert/ticket distribution.

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).

documenting procedures for log management (including references to 8.15/8.17) is a governance dependency that other controls may act on; it does not itself stop excessive data from being logged or hinder exploitation of that weakness
