Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-23816 is a vulnerability in the command line interface of AOS-CX Switches that could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system. Classified under CWE-78 (OS Command Injection), it received a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) upon publication on March 11, 2026.
The vulnerability can be exploited by an authenticated remote attacker possessing high privileges, such as an administrative user, over the network with low attack complexity and no user interaction required. Successful exploitation enables the attacker to achieve high impacts on confidentiality, integrity, and availability, potentially granting full control over the underlying operating system.
HPE has published a security advisory providing details on the vulnerability and mitigation measures at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw05027en_us&docLocale=en_US.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
