An attacker could exploit these vulnerabilities to obtain and modify sensitive information in the underlying database potentially leading to complete compromise of the ClearPass Policy Manager cluster. Internal references: ATLCP-177, ATLCP-178, ATLCP-180 ATLCP-201, ATLCP-202 Severity: High CVSSv3 Overall Score: 8.8 CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Discovery: These vulnerabilities were discovered and reported by Luke Young (bugcrowd.com/bored-engineer) and Daniel Jensen (@dozernz) via Aruba’s Bug Bounty Program Lack of Cross-Site Request Forgery (CSRF) Protections for some Endpoints in ClearPass Policy Manager (CVE-2022-23685) --------------------------------------------------------------------- A vulnerability in the ClearPass Policy Manager web-based management interface exists which exposes some endpoints to a lack of Cross-Site Request Forgery (CSRF) protection. This could allow a remote unauthenticated attacker to execute arbitrary input against these endpoints if the attacker can convince an authenticated user of the interface to interact with a specially crafted URL. Internal References: ATLCP-219 Severity: High CVSSv3.x Overall Score: 8.1 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N Discovery: This vulnerability was discovered and reported by the Aruba ClearPass Policy Manager Engineering Team. Local Privilege Escalation in ClearPass OnGuard macOS Agent (CVE-2022-37877) --------------------------------------------------------------------- A vulnerability in the ClearPass OnGuard macOS agent could allow malicious users on a macOS instance to elevate their user privileges. A successful exploit could allow these users to execute arbitrary code with root level privileges on the macOS instance. Internal references: ATLCP-205 Severity: High CVSSv3 Overall Score: 8.0 CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L Discovery: This vulnerability was discovered and reported by Luke Young (bugcrowd.com/bored_engineer) via Aruba’s Bug Bounty Program. Authenticated Remote Command Injection in ClearPass Policy Manager Web-Based Management Interface (CVE-2022-37878, CVE-2022-37879, CVE-2022-37880, CVE-2022-37881, CVE-2022-37882, CVE-2022-37883) --------------------------------------------------------------------- Vulnerabilities in the ClearPass Policy Manager web-based management interface allow remote authenticated users to run arbitrary commands on the underlying host. A successful exploit could allow an attacker to execute arbitrary commands as root on the underlying operating system leading to complete system compromise. Internal References: ATLCP-166, ATLCP-179, ATLCP-183, ATLCP-189, ATLCP-193, ATLCP-197 Severity: High CVSSv3.x Overall Score: 7.2 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H Discovery: These vulnerabilities were discovered and reported by Daniel Jensen (@dozernz) via Aruba’s Bug Bounty Program. Unauthenticated Denial-of-Service Condition in ClearPass Policy Manager Guest User Interface (CVE-2022-37884) -------------------------------------------------------------------- A vulnerability exists in the ClearPass Policy Manager Guest User Interface that can allow an unauthenticated attacker to send specific operations which result in a Denial-of-Service condition. A successful exploitation of this vulnerability results in the unavailability of the guest interface. Internal Reference: ATLCP-167 Severity: Medium CVSSv3.x Overall Score: 5.3 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L Discovery: This vulnerability was discovered and reported by Daniel Jensen (@dozernz) via Aruba’s Bug Bounty Program.
