Aruba Mobility Conductor (formerly Mobility…: Stack-based Buffer Overflow
CVE-2024-33515 is a high-severity stack-based buffer overflow 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 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Aruba Mobility Conductor (formerly Mobility Master); Aruba Mobility Controllers; WLAN Gateways and SD-WAN Gateways managed by Aruba Central versions: ArubaOS 10.5.x.x: 10.5.1.0 and below; ArubaOS 10.4.x.x: 10.4.1.0 and below; ArubaOS 8.11.x.x: 8.11.2.1 and below, 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 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update arubaos to 8.10.0.10 or 10.5.1.0 or 10.4.1.0 or 8.11.2.1, 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
Unauthenticated Denial-of-Service (DoS) vulnerabilities exist in the AP Management service accessed via the PAPI protocol. Successful exploitation of these vulnerabilities results in the ability to interrupt the normal operation of the affected service.

The underlying weakness: Stack-based Buffer Overflow
The product writes past the end of a buffer that was allocated on the stack.
How developers prevent this class of flaw
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
- Implement and perform bounds checking on input.
