Summary

CVE-2024-32765 is a medium-severity Reliance on IP Address for Authentication (CWE-291) vulnerability in Qnap Qts. Its CVSS base score is 4.2 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11th 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 AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

Requires unique identification and authentication of users rather than permitting unauthenticated or spoofable attributes such as source IP.

Requires unique identification and authentication of non-organizational users, precluding reliance on IP address alone.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

AC-17 Remote Access partial match

Mandates documented usage restrictions and configuration requirements for remote access that cannot be satisfied by IP-based authentication.

Access enforcement requires prior authentication before any authorization decision for critical functions.

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

Strong authentication mechanisms directly replace reliance on spoofable IP addresses.

PR.AA-01 mostly match
prevents

Managed identities and credentials supplant weak IP-based authentication decisions.

DE.CM-01 partial match
prevents

Network monitoring can detect misuse of IP authentication but does not prevent the weakness.

PR.AA-05 partial match
prevents

Authorization policies and least privilege reduce dependence on network-location assertions.

PR.IR-01 partial match
prevents

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

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.

prevents

The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.

prevents

Access-control policy can mandate stronger authentication than IP address alone.

prevents

Identity-management processes should replace IP-based identification with verified identities.

degrades

Authentication-information rules discourage reliance on mutable attributes such as IP addresses.

prevents

Access-rights assignment should be tied to authenticated identities, not network location.

prevents

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.
