Summary

CVE-2022-3229 is a critical-severity Improper Authorization (CWE-285) vulnerability in Unifiedremote Unified Remote. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability affects the web management interface of Unified Intents' Unified Remote solution. Because the interface does not require authentication, an unauthenticated remote attacker can modify or disable authentication requirements on the Unified Remote protocol itself, ultimately enabling arbitrary code execution on the affected system. The issue is tracked as CVE-2022-3229 with a CVSS 3.1 base score of 9.8 and is associated with missing authentication weaknesses (CWE-285 and CWE-306).

A remote attacker with no credentials can directly target the web interface over the network to alter protocol authentication settings and then execute attacker-supplied code. This scenario requires no user interaction and grants full confidentiality, integrity, and availability impact once the protocol is left unauthenticated.

The EPSS score for the vulnerability rose from a low baseline to a peak of 0.8873 on 2025-12-11 before receding to the current value of 0.7219, indicating that exploitation interest increased substantially after public disclosure. Public references consist of Metasploit Framework pull requests that add an exploit module for the issue.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authentication on the web management interface so an unauthenticated attacker cannot alter Unified Remote protocol authentication settings.

prevent

Requires unique identification and authentication of users before any access to the management interface is granted, eliminating the unauthenticated entry point.

prevent

Limits the set of actions (such as changing protocol authentication) that are permitted without prior identification and authentication.

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

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-05 mostly match
prevents

PR.AA-05 mostly prevents CWE-285 via enforced policy, reviews, and least-privilege authorization decisions, yet CWE-285 remains only partially prevented because code-level check omissions or errors can still occur outside that single control.

PR.PS-06 mostly match
prevents

Secure SDLC practices catch and eliminate most authorization defects before release, yet a single broad outcome cannot address every design, role, and runtime facet of CWE-285.

PR.AA-01 partial match
prevents

PR.AA-01 supplies managed identities and access-request workflows that can support downstream authorization decisions, yet does nothing to enforce or verify authorization checks inside a product, leaving CWE-285 fully unaddressed by this control alone.

PR.IR-01 partial match
prevents

Network segmentation/zero-trust limits external reachability (partial prevention of exploitation) but leaves application-level authorization logic untouched, so the CWE remains fully introducible and only one facet of its risk is addressed.

PR.PS-05 none match
prevents

PR.PS-05 blocks unauthorized binaries/DNS while CWE-285 is an in-product authorization-check defect, so the control neither prevents the weakness nor removes any of its risk.

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

Granular, policy-driven assignment of permissions and dynamic enforcement of those permissions prevent the incorrect or missing authorization decisions that lead to improper authorization flaws.

prevents

By requiring documented authorization rules and periodic policy reviews, the control makes it less likely that authorization decisions will be omitted or implemented inconsistently across applications.

prevents

Mapping access rights to information classification and business requirements forces correct enforcement of authorization decisions, blocking the incorrect authorization weakness at the policy and implementation stage.

detects

Independent reviewers evaluate whether authorization logic matches policy, thereby reducing the window in which incorrect or missing authorization checks remain in production.

detects

By requiring managers to verify that authorization decisions match policy and to remediate deviations, the control limits the persistence of incorrect or missing authorization checks.
