Published: 01 February 2023
Summary
CVE-2022-47003 is a critical-severity Improper Authentication (CWE-287) vulnerability in Murasoftware Mura Cms. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 3.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A vulnerability in the Remember Me function of Mura CMS before version 10.0.580 permits authentication bypass through a crafted web request. The flaw affects the open-source content management system and carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation with no required credentials or user interaction and full compromise of confidentiality, integrity, and availability.
An unauthenticated attacker can send a specially formed request to the affected Remember Me endpoint and obtain a valid authenticated session. Successful exploitation grants the attacker the same privileges as the impersonated user, enabling arbitrary administrative actions within the CMS instance.
Advisories referenced in the disclosure point to Mura CMS 10.0.580 and later releases as containing the fix, with additional technical details published on security-research blogs. The associated EPSS score rose from lower values after public disclosure to a peak of 0.3028 on 2025-12-11 before receding to the current 0.2444, indicating measurable post-disclosure exploitation interest.

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.
