Details Unauthenticated Stored Cross-Site Scripting in ArubaOS-Switch (CVE-2023-39266) A vulnerability in the ArubaOS-Switch web management interface could allow an unauthenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface provided certain configuration options are present. A successful exploit could allow an attacker to execute arbitrary script code in a victim's browser in the context of the affected interface. Internal Reference: APVOS-13 Severity: High CVSSv3 Overall Score: 8.3 CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H Discovery: This vulnerability was discovered and reported by Ken Pyle - Partner and Exploit Developer, CYBIR and Graduate Professor of Cybersecurity at Chestnut Hill College Workaround: With configuration changes, such as setting an operator password on the switch and enforcing the use of HTTPS prevents this attack. Please see the ArubaOS-Switch hardening guide at https://support.hpe.com/hpesc/public/docDisplay?docId=a00056155en_us for details. Additionally, disabling the web management interface prevents this attack. Contact HPE Services - Aruba Networking TAC for any configuration Assistance. Authenticated Denial of Service Vulnerability in ArubaOS-Switch Command Line Interface (CVE-2023-39267) An authenticated remote code execution vulnerability exists in the command line interface in ArubaOS-Switch. Successful exploitation results in a Denial-of-Service (DoS) condition in the switch. Internal reference: APVOS-18 Severity: Medium CVSSv3 Overall Score: 6.6 CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:L Discovery: This vulnerability was discovered by Lino Mirgeler of DTS Systeme GmbH Memory Corruption Vulnerability in ArubaOS-Switch (CVE-2023-39268) A memory corruption vulnerability in ArubaOS-Switch could lead to unauthenticated remote code execution by receiving specially crafted packets. Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system. Internal References: APVOS-17 Severity: Medium CVSSv3 Overall Score: 4.5 CVSS Vector: CVSSv3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:H Discovery: This vulnerability was discovered and reported by Ken Pyle - Partner and Exploit Developer, CYBIR and Graduate Workaround To minimize the likelihood of an attacker exploiting these vulnerabilities, HPE Aruba Networking recommends that the CLI and web-based management interfaces be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above. Contact HPE Services - Aruba Networking TAC for any configuration assistance.
