HPE Integrated Lights-Out 5 (iLO 5): Improper Control of Generation of Code
CVE-2022-28640 is a high-severity improper control of generation of code vulnerability in HPE Integrated Lights-Out 5 (iLO 5), with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected HPE Integrated Lights-Out 5 (iLO 5) versions: Prior to 2.72. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.55% 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 Integrated Lights-out 5 Firmware to 2.72 or a later version.
- Read the advisory on support.hpe.com for workarounds and exact fixed builds.

Official description
A potential local adjacent arbitrary code execution vulnerability that could potentially lead to a loss of confidentiality, integrity, and availability was discovered in HPE Integrated Lights-Out 5 (iLO 5) in Version: 2.71. Hewlett Packard Enterprise has provided updated firmware for HPE Integrated Lights-Out 5 (iLO 5) that addresses this security vulnerability.

The underlying weakness: Improper Control of Generation of Code
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
How developers prevent this class of flaw
- Refactor your program so that you do not have to dynamically generate code.
- Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
- Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
