AOS-8 Instant and AOS-10 AP: Deletion of Data Structure Sentinel
CVE-2024-31475 is a high-severity deletion of data structure sentinel vulnerability in AOS-8 Instant and AOS-10 AP from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected AOS-8 Instant and AOS-10 AP versions: 10.5.0.0 through 10.5.1.0; 10.4.0.0 through 10.4.1.0; 8.11.0.0 through 8.11.2.1, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update arubaos to 10.4.0.0 or a later version.
- Update instant to 8.10.0.0 or 8.9.0.0 or 8.6.0.0 or 8.8.0.0, whichever matches your release line, or a later version.
- Update Instantos to 8.6.0.24 or 8.10.0.11, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
There is an arbitrary file deletion vulnerability in the Central Communications service accessed by PAPI (Aruba's access point management protocol). Successful exploitation of this vulnerability results in the ability to delete arbitrary files on the underlying operating system, which could lead to the ability to interrupt normal operation and impact the integrity of the affected Access Point.

The underlying weakness: Deletion of Data Structure Sentinel
The accidental deletion of a data-structure sentinel can cause serious programming logic problems.
How developers prevent this class of flaw
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
- Run or compile the software using features or extensions that automatically provide a protection mechanism that mitigates or eliminates buffer overflows. For example, certain compilers and extensions provide automatic buffer overflow detection mechanisms that are built into the compiled code. Examples include the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice.
- Use OS-level preventative functionality. Not a complete solution.
