CVE-2022-24422
Published: 26 May 2022
Summary
CVE-2022-24422 is a critical-severity Improper Authentication (CWE-287) vulnerability in Dell Idrac9. Its CVSS base score is 9.6 (Critical).
Operationally, ranked in the top 5.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Dell iDRAC9 versions 5.00.00.00 through 5.10.10.00 contain an improper authentication vulnerability tracked as CVE-2022-24422 and CWE-287. The flaw resides in the remote management interface and permits unauthorized access to the integrated VNC console without requiring credentials.
A remote unauthenticated attacker can exploit the weakness over the network by sending crafted requests that bypass authentication checks, resulting in full control of the VNC session. Successful exploitation yields high impact across confidentiality, integrity, and availability, reflected in the CVSS 9.6 score with network attack vector and no required privileges or user interaction.
Dell security advisory DSA-2022-068 addresses the issue by directing customers to upgrade iDRAC9 firmware to version 5.10.10.00 or later, which restores proper authentication enforcement for the VNC console.
EPSS for the CVE rose from lower values to a peak of 0.3780 on 2025-12-11 before receding to the current 0.1579, indicating a period of increased exploitation interest after disclosure.

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.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
