===================================================================== CERT-Renater Note d'Information No. 2023/VULN433 _____________________________________________________________________ DATE : 25/10/2023 HARDWARE PLATFORM(S): / OPERATING SYSTEM(S): Systems running ClearPass Policy Manager versions prior to 6.11.5, 6.10.8 Hotfix Q4 2023 for Security issues, 6.9.13 Hotfix Q4 2023 for Security issues. ===================================================================== https://www.arubanetworks.com/assets/alert/ARUBA-PSA-2023-016.txt _____________________________________________________________________ HPE Aruba Networking Product Security Advisory =============================== Advisory ID: ARUBA-PSA-2023-016 CVE: CVE-2023-43506, CVE-2023-43507, CVE-2023-43508, CVE-2023-43509, CVE-2023-43510 Publication Date: 2023-Oct-24 Status: Confirmed Severity: High Revision: 1 Title ===== ClearPass Policy Manager Multiple Vulnerabilities Overview ======== HPE Aruba Networking has released updates to ClearPass Policy Manager that address multiple security vulnerabilities. Affected Products ================= These vulnerabilities affect ClearPass Policy Manager running the following software versions unless specifically noted otherwise in the details section: - ClearPass Policy Manager 6.11.x: 6.11.4 and below - ClearPass Policy Manager 6.10.x: 6.10.8 with ClearPass 6.10.8 Cumulative Hotfix Patch 5 and below - ClearPass Policy Manager 6.9.x: 6.9.13 with ClearPass 6.9.13 Cumulative Hotfix Patch 3 and below Versions of ClearPass Policy Manager that are end of life are affected by these vulnerabilities unless otherwise indicated. Unaffected Products =================== Any other HPE Aruba Networking products not specifically listed above are not affected by these vulnerabilities. Details ======= Local Privilege Escalation in ClearPass OnGuard Linux Agent (CVE-2023-43506) --------------------------------------------------------------------- A vulnerability in the ClearPass OnGuard Linux agent could allow malicious users on a Linux instance to elevate their user privileges to those of a higher role. A successful exploit allows malicious users to execute arbitrary code with root level privileges on the Linux instance. Internal references: ATLCP-248 Severity: High CVSSv3 Overall Score: 7.8 CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Discovery: This vulnerability was discovered and reported by Luke Young (bugcrowd.com/bored_engineer) via Aruba's Bug Bounty Program. Workaround: None Authenticated SQL Injection Vulnerability in ClearPass Policy Manager Web-based Management Interface (CVE-2023-43507) --------------------------------------------------------------------- A vulnerability in the web-based management interface of ClearPass Policy Manager could allow an authenticated remote attacker to conduct SQL injection attacks against the ClearPass Policy Manager instance. An attacker could exploit this vulnerability to obtain and modify sensitive information in the underlying database potentially leading to complete compromise of the ClearPass Policy Manager cluster. Internal references: ATLCP-255 Severity: High CVSSv3 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: This vulnerability was discovered and reported by Luke Young (bugcrowd.com/bored_engineer) via Aruba's Bug Bounty Program. Workaround: To minimize the likelihood of an attacker exploiting this vulnerability, HPE Aruba Networking recommends that the web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above. Authorization Bypass Leading to Privilege Escalation in ClearPass Policy Manager Web-Based Management Interface (CVE-2023-43508) --------------------------------------------------------------------- Vulnerabilities in the web-based management interface of ClearPass Policy Manager allow an attacker with read-only privileges to perform actions that change the state of the ClearPass Policy Manager instance. Successful exploitation of these vulnerabilities allow an attacker to complete state-changing actions in the web-based management interface that should not be allowed by their current level of authorization on the platform. Internal References: ATLCP-238, ATLCP-239, ATLCP-240, ATLCP-244 Severity: Medium CVSSv3.x Overall Score: 6.3 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L Discovery: These vulnerabilities were discovered and reported by Mateusz Dabrowski (dbrwsky). Workaround: To minimize the likelihood of an attacker exploiting this vulnerability, HPE Aruba Networking recommends that the web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above. Unauthenticated Endpoint Allows Sending Arbitrary OnGuard Notifications (CVE-2023-43509) --------------------------------------------------------------------- A vulnerability in the web-based management interface of ClearPass Policy Manager could allow an unauthenticated remote attacker to send notifications to computers that are running ClearPass OnGuard. These notifications can then be used to phish users or trick them into downloading malicious software. Internal references: ATLCP-233 Severity: Medium CVSSv3 Overall Score: 5.8 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N Discovery: This vulnerability was discovered and reported by Luke Young (bugcrowd.com/bored-engineer) via Aruba's Bug Bounty Program. Workaround: To minimize the likelihood of an attacker exploiting this vulnerability, HPE Aruba Networking recommends that the web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above. Authenticated Remote Command Injection in ClearPass Policy Manager Web-Based Management Interface Leading to Partial System Compromise (CVE-2023-43510) --------------------------------------------------------------------- A vulnerability in the ClearPass Policy Manager web-based management interface allows remote authenticated users to run arbitrary commands on the underlying host. A successful exploit could allow an attacker to execute arbitrary commands as a non-privileged user on the underlying operating system leading to partial system compromise. Internal References: ATLCP-230 Severity: Medium CVSSv3.x Overall Score: 4.7 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L Discovery: This vulnerability was discovered and reported by Daniel Jensen (@dozernz) via Aruba's Bug Bounty Program. Workaround: To minimize the likelihood of an attacker exploiting this vulnerability, HPE Aruba Networking recommends that the web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above.
