Summary

CVE-2026-23593 is a high-severity Path Traversal (CWE-22) vulnerability in Hpe (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 49th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-23593 is a path traversal vulnerability (CWE-22) in the web-based management interface of HPE Aruba Networking Fabric Composer. It enables an unauthenticated remote attacker to view some system files by reading files within the affected directory. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and was published on 2026-01-27T18:15:56.517.

An unauthenticated remote attacker can exploit this vulnerability over the network with low attack complexity and no user interaction or privileges required. Successful exploitation allows the attacker to read files within the affected directory, potentially disrupting availability as indicated by the high impact score.

The HPE security advisory provides details on mitigation and patches at https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04996en_us&docLocale=en_US. Security practitioners should consult this reference for specific remediation steps.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
