CVE-2022-37886

There are buffer overflow vulnerabilities in multiple underlying services that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba Networks AP management protocol) UDP port (8211). Successful exploitation of these vulnerabilities results in the ability to execute arbitrary code as a privileged user on the underlying operating system of Aruba InstantOS 6.4.x: 6.4.4.8-4.2.4.20 and below; Aruba InstantOS 6.5.x: 6.5.4.23 and below; Aruba InstantOS 8.6.x: 8.6.0.18 and below; Aruba InstantOS 8.7.x: 8.7.1.9 and below; Aruba InstantOS 8.10.x: 8.10.0.1 and below; ArubaOS 10.3.x: 10.3.1.0 and below; Aruba has released upgrades for Aruba InnstantOS that address these security vulnerabilities.

Base score Version Severity Vector Exploitability Impact Score source
9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
