CVE-2026-23592
Published: 27 January 2026
Summary
CVE-2026-23592 is a high-severity OS Command Injection (CWE-78) vulnerability in Hpe (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 33.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-23592 involves insecure file operations in the backup functionality of HPE Aruba Networking Fabric Composer, enabling remote code execution. Published on 2026-01-27, this vulnerability is rated at 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) and is associated with CWE-78 (OS Command Injection). It affects the Fabric Composer's implementation, where flaws in handling file operations during backups expose the system to exploitation.
Authenticated attackers with high privileges (PR:H) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and without requiring user interaction (UI:N). Successful exploitation allows the execution of arbitrary commands on the underlying operating system, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U).

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs and file operations to block OS command injection in the backup functionality.
Enforces least privilege so that even authenticated users lack the elevated rights needed to trigger the RCE via backup file operations.
Restricts access and changes to system files and backup mechanisms, limiting an attacker's ability to exploit insecure file handling.
