CVE-2022-22948 is an information disclosure vulnerability found in VMware's vCenter Server. It arises from improper permission settings on files, allowing a malicious actor with non-administrative access to exploit this issue and gain unauthorized access to sensitive information.
The severity of this vulnerability is classified as medium, with a CVSS score of 6.5. This rating indicates a significant risk, as attackers may leverage such vulnerabilities to extract confidential data without the need for elevated privileges.
Organizations using affected versions of vCenter Server should prioritize addressing this vulnerability. The urgency is underscored by its inclusion in the Known Exploited Vulnerabilities (KEV) catalog, which suggests that it is actively targeted for exploitation.
Organizations should prioritize patching immediately to prevent potential data breaches and ensure the integrity of their systems.
Vulnerability Details
The vCenter Server contains an information disclosure vulnerability due to improper permission of files. A malicious actor with non-administrative access to the vCenter Server may exploit this issue to gain access to sensitive information.
This vulnerability is classified as CWE-276, which focuses on improper permissions. It has a CVSS score of 6.5, indicating a medium severity level. The vulnerability affects the VMware vCenter Server and has been publicly disclosed on March 29, 2022.
Technical Analysis
The root cause of this vulnerability is the improper configuration of file permissions within the vCenter Server. This misconfiguration allows unauthorized users to access sensitive files that should be restricted to administrative users only.
The attack vector is network-based, requiring only low complexity for exploitation. Attackers need low privileges and do not require user interaction to exploit this vulnerability. The impact on confidentiality is classified as high, while integrity and availability impacts are rated as none.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive information, which could lead to data breaches and non-compliance with data protection regulations. Given the nature of the vulnerability, the potential blast radius is significant, particularly for organizations handling sensitive data.
Due to its inclusion in the KEV catalog, organizations should assess their exposure to this vulnerability and prioritize remediation efforts accordingly. The urgency is critical, and organizations should address this in their patch cycle.
