HPE Compute Scale-up Server 3200 platform: Improper Neutralization of Special Elements used in an OS Command
CVE-2026-76740 is a high-severity improper neutralization of special elements used in an OS command vulnerability in HPE Compute Scale-up Server 3200 platform from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 1.77.30 as the first without the flaw, so updating HPE Compute Scale-up Server 3200 platform to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.48% 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 HPE Compute Scale-up Server 3200 platform to 1.77.30 or a later version.
- Update HPE Compute Scale-up Server 3250 platform to 1.03.38 or a later version.
- Update HPE Superdome Flex server to 4.17.03 or a later version.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
