CVE-2022-21196
Published: 18 February 2022
Summary
CVE-2022-21196 is a critical-severity Improper Authorization (CWE-285) vulnerability in Airspan Mimosa Management Platform. Its CVSS base score is 10.0 (Critical).
Operationally, ranked in the top 31.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2022-21196 affects Cambium Networks MMP software prior to version 1.0.3 as well as PTP C-series devices prior to 2.8.6.1 and PTMP C-series and A5x devices prior to 2.5.4.1. The flaw stems from missing authorization and authentication checks across multiple API routes, allowing unauthenticated network callers to reach privileged functionality that should have been restricted.
An attacker with network access to the affected devices or management platform can invoke the unprotected endpoints to execute arbitrary code, induce denial-of-service conditions, or extract sensitive configuration and operational data. Because the CVSS vector shows an unauthenticated, network-reachable attack with no user interaction required, exploitation can occur remotely without credentials or prior foothold.
CISA advisory ICSA-22-034-02 directs operators to upgrade MMP to 1.0.3 or later and the listed device families to the specified patched releases; it further recommends restricting management-plane access and monitoring API traffic until patches can be applied.
The EPSS score rose sharply from a low baseline to a peak of 0.2138 in January 2025 before receding, indicating that exploitation interest materialized well after the original 2022 disclosure and that the vulnerability merits renewed attention.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Role-based training addresses authorization requirements and checks, lowering the risk of improper authorization.
Auditing session actions allows identification of improper authorization decisions and enforcement failures.
Audit analysis reports findings of improper authorization, reducing the impact of such weaknesses.
Documenting authorization requirements and responsibilities for each exchange ensures authorization decisions are explicitly defined and managed.
Reconstitution restores proper authorization policies and enforcement that may have been altered.
Supplies backup authorization methods to block unauthorized actions when the primary authorization process is unavailable or compromised.
Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
Mandates authorization for identifier assignment, reducing risks of improper authorization.
