Affected Products ================= Aruba Mobility Conductor (formerly Mobility Master), Aruba Mobility Controllers, Access-Points when managed by Mobility Controllers and Aruba SD-WAN Gateways. Affected versions: Not all vulnerabilities in this advisory affect all ArubaOS branches. If an ArubaOS branch is not listed as affected, it means that any ArubaOS version in that given branch is not affected. For example, the 6.4.x.x and 6.5.x.x branches are not affected by CVE-2021-37717. Updating a branch of ArubaOS to the version listed in the Resolution section at the end of this advisory resolve all known issues with that branch. Versions of ArubaOS and SD-WAN that are end of life should be considered to be affected by these vulnerabilities. Impacted customers should plan to migrate to a supported branch. Branches that should be considered to be vulnerable and are not patched by this advisory include: - ArubaOS 8.0.x.x - ArubaOS 8.1.x.x - ArubaOS 8.2.x.x - ArubaOS 8.4.x.x - SD-WAN 1.0.x.x - SD-WAN 2.0.x.x - SD-WAN 2.1.x.x Details ======= Buffer Overflow Vulnerabilities in the PAPI protocol (CVE-2021-37716) --------------------------------------------------------------------- There are multiple buffer overflow vulnerabilities that could lead to unauthenticated remote code execution by sending especially crafted packets destined to the PAPI (Aruba Networks AP management protocol) UDP port (8211) of devices running ArubaOS. This may potentially allow for denial-of-service attacks and/or remote code execution in the underlying operating system.

For more information about Aruba's End of Support policy visit: https://www.arubanetworks.com/support-services/end-of-life/ Workaround ========== In order to minimize the likelihood of an attacker exploiting these vulnerabilities, Aruba recommends that the communication between Controller/Gateways and Access-Points be restricted either by having a dedicated layer 2 segment/VLAN or, if Controller/Gateways and Access-Points cross layer 3 boundaries, to have firewall policies restricting the communication of these authorized devices. Also, enabling the Enhanced PAPI Security feature will prevent the PAPI-specific vulnerabilities above from being exploited. Contact Aruba Support for configuration assistance.
