Summary

CVE-2023-42130 is a high-severity Path Traversal (CWE-22) vulnerability in A10Networks Advanced Core Operating System. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 20% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

Deeper analysis AI-assisted summary

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

CVE-2023-42130 is a directory traversal vulnerability in the FileMgmtExport class of A10 Thunder ADC that permits arbitrary file read and deletion. The flaw stems from insufficient validation of user-supplied paths before they are used in file operations, and it carries a CVSS 3.1 score of 8.8 with CWE-22.

Authenticated remote attackers can exploit the issue to read or delete arbitrary files on affected installations in the context of the service account. No unauthenticated access vector is described.

A10 Networks has published a security advisory for the file-access vulnerability, available alongside the Zero Day Initiative disclosure at the referenced URLs. The EPSS score has remained at 0.1131 with no material increase after disclosure.

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.
