Release Date: 2022-05-03 Last Updated: 2022-06-22 Potential Security Impact: Remote: Arbitrary Code Execution Source: Hewlett Packard Enterprise, HPE Product Security Response Team VULNERABILITY SUMMARY Title Heap Overflow Vulnerabilities Within AOS-S Devices Note: Information originally published in ARUBA-PSA-2022-008 Aruba Product Security Advisory =============================== Advisory ID: ARUBA-PSA-2022-008 CVE: CVE-2022-23676, CVE-2022-23677 Publication Date: 2022-May-03 Last Update: 2022-Jun-21 Status: Confirmed Severity: Critical Revision: 3 Overview The Armis Research Team has discovered multiple heap overflow vulnerabilities with various networking vendors. ArubaOS-Switch devices are affected by these vulnerabilities in the affected versions. Exploitation of these vulnerabilities allow for attackers to execute arbitrary code on the affected device. More information about these vulnerabilities can be found at: https://www.armis.com/research/tlstorm/ Affected Products Customers using the following switch models and firmware versions are affected by the vulnerabilities listed in this advisory. Aruba Switch Models: Aruba 2530 Series Switches Aruba 2540 Series Switches Aruba 2615 Series Switches Aruba 2620 Series Switches Aruba 2915 Series Switches Aruba 2920 Series Switches Aruba 2930F Series Switches Aruba 2930M Series Switches Aruba 3800 Series Switches Aruba 3810 Series Switches Aruba 5400 Series Switches Aruba 5400R Series Switches Software branch versions: AOS-S 15.xx.xxxx: A.15.16.0023 and below.

Unaffected Products Any other Aruba products not listed above, including other models of AOS-S Switches, AOS-CX Switches, Aruba Intelligent Edge Switches and HPE OfficeConnect Switches are not affected by these vulnerabilities. Details Heap Overflow Vulnerabilities in RADIUS EAP Messages (CVE-2022-23676) Multiple heap overflow vulnerabilities have been discovered in the AOS-S firmware. Successful exploitation of these vulnerabilities could result in the ability to execute arbitrary code. Exploitation of these vulnerabilities requires an attacker-controlled RADIUS server capable of sending access challenge messages to an affected switch. Because of this, exploitation of these vulnerabilities would most likely occur as part of an attack chain building upon previous exploitation of customer controlled infrastructure. Only AOS-S devices that are configured to use RADIUS are affected by these vulnerabilities. Internal reference: APVOS-14 Severity: Critical CVSSv3.1 Overall Score: 9.1 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H Heap Overflow Vulnerabilities in Mocana Cryptographic Library (CVE-2022-23677) Multiple heap overflow vulnerabilities related to the Mocana cryptographic library have been discovered in the AOS-S firmware. Some of these vulnerabilities also affect the Web-Based Management Interface and the captive portal of the affected devices. Successful exploitation of these vulnerabilities could result in the ability to execute arbitrary code. Internal Reference: APVOS-15 Severity: Critical CVSSv3.1 Overall Score: 9.0 CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H Exploitation and Public Discussion This Aruba Product Security Advisory is part of a coordinated disclosure with the Armis Research team and the details of the vulnerabilities can be found here: https://www.armis.com/research/tlstorm/ References: CVE-2022-23676 CVE-2022-23677 SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.

RESOLUTION The vulnerabilities contained in this advisory can be addressed by patching or upgrading to one of the ArubaOS versions listed below. AOS-S 15.16.xxxx: A.15.16.0024 and above. AOS-S 16.02.xxxx: K.16.02.0035 and above. AOS-S 16.04.xxxx: KA/RA.16.04.0025 and above. AOS-S 16.08.xxxx: KB/WB/WC/YA/YB/YC.16.08.0026 and above.

Workarounds For CVE-2022-23676, Aruba recommends implementing firewall controls to limit interactions of impacted switches with known good RADIUS sources. For CVE-2022-23677, Aruba recommends that the web-based management interfaces for switches to be restricted to a dedicated layer 2segment/VLAN and/or controlled by firewall policies at layer 3 and above. Alternatively, users can disable the web-based management interface. Customers who enabled captive portal on affected switches are also exposed to this issue. Until final patches are issued, Aruba recommends that the captive portal URL accessed by affected switches be restricted to a dedicated layer 2 segment/VLAN and/or controlled by firewall policies at layer 3 and above that only allows HTTP traffic from approved clients.
