Summary

CVE-2024-1886 is a low-severity Path Traversal: '.../...//' (CWE-35) vulnerability in Lg Webos Signage. Its CVSS base score is 3.0 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

SI-10 Information Input Validation good match

Input validation directly neutralizes path sequences so the traversal cannot be introduced or exploited.

AC-4 Information Flow Enforcement partial match

Enforces information flow rules that stop unauthorized directory escapes via crafted paths.

AC-6 Least Privilege partial match

Least privilege reduces the impact of any successful traversal by limiting accessible resources.

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 input validation and path sanitization that neutralize traversal sequences.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect path-traversal flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for safe file-path construction and canonicalization.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits file reachability but does not address the input-validation flaw itself.
