Aruba Mobility Conductor (formerly Mobility…: Write-what-where Condition
CVE-2022-37904 is a high-severity write-what-where condition vulnerability in Aruba Mobility Conductor (formerly Mobility Master); Aruba Mobility Controllers; WLAN Gateways and SD-WAN Gateways managed by Aruba Central from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. There is no confirmed exploitation so far. EPSS estimates a 0.89% chance of exploitation within 30 days, higher than 60% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Sd-wan to 8.7.0.0-2.3.0.7 or a later version.
- Update Arubaos to 6.5.4.23 or 8.6.0.18 or 8.7.1.10 or 8.10.0.0, whichever matches your release line, or a later version.

Official description
Vulnerabilities in ArubaOS running on 7xxx series controllers exist that allows an attacker to execute arbitrary code during the boot sequence. Successful exploitation could allow an attacker to achieve permanent modification of the underlying operating system.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Write-what-where Condition
Any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
- Use OS-level preventative functionality integrated after the fact. Not a complete solution.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
