Summary

CVE-2024-47010 is a high-severity Path Traversal (CWE-22) vulnerability in Ivanti Avalanche. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-25 (Reference Monitor) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-25 Reference Monitor good match

Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.

AC-3 Access Enforcement good match

Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.

IA-2 Identification and Authentication (Organizational Users) good match

Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.

SI-10 Information Input Validation good match

Input validation directly neutralizes special path elements before pathname construction occurs.

AC-6 Least Privilege partial match

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

SC-7 Boundary Protection partial match

Controls all external and key internal interfaces, reducing the chance of unauthenticated alternate channels.

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.AA-03 full match
prevents

Requiring authentication on every channel and path directly eliminates alternate-path bypasses.

PR.AA-05 mostly match
prevents

Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.

PR.IR-01 mostly match
prevents

Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.

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.

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

Security testing in development catches path traversal via static/dynamic analysis.

A.8.5 Secure authentication mostly match
degrades

Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.

A.5.15 Access control partial match
prevents

Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.

A.5.17 Authentication information partial match
degrades

Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.

A.5.18 Access rights partial match
prevents

Access rights provisioning and review prevent bypass via unmonitored or alternate channels.

A.8.2 Privileged access rights partial match
prevents

Privileged access rights control reduces risk of bypass through elevated or alternate paths.
