CVE-2016-8526

Exp

Aruba Airwave all versions up to, but not including, 8.2.3.1 is vulnerable to an XML external entities (XXE). XXEs are a way to permit XML parsers to access storage that exist on external systems. If an unprivileged user is permitted to control the contents of XML files, XXE can be used as an attack vector. Because the XML parser has access to the local filesystem and runs with the permissions of the web server, it can access any file that is readable by the web server and copy it to an external system of the attacker's choosing. This could include files that contain passwords, which could then lead to privilege escalation.

Base score Version Severity Vector Exploitability Impact Score source
8.8 3.0 HIGH
CVSS:3.0/AV:N/AC:L/PR:L/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:L)
A normal user session is enough; they don’t have to be admin.
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.
