Summary

CVE-2024-23569 is a medium-severity Incomplete Denylist to Cross-Site Scripting (CWE-692) vulnerability in Hcl Software (inferred from references). Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked at the 7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation requires complete, allowlist-style checks that structurally eliminate reliance on incomplete XSS denylists.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles mandate robust sanitization and validation approaches that avoid incomplete denylist patterns.

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.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require robust input validation and sanitization (e.g., allowlists) rather than incomplete denylists for XSS.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can discover incomplete denylists, yet the control does not mandate their replacement.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC processes encourage proper input/output handling, but do not specifically address denylist shortcomings.

A.8.26 Application security requirements partial match
prevents

Application-security requirements can mandate proper output encoding, but the control itself does not prescribe the technique.

A.8.28 Secure coding partial match
prevents

Secure-coding rules directly require allow-list or context-aware escaping instead of incomplete denylists for XSS.
