Network Security Manager Nsm
Monthly
Arbitrary file write via Zip Slip in SonicWall Network Security Manager (NSM) On-Prem (versions 4.3.0 and earlier) allows an authenticated attacker to extract archive entries outside the intended destination directory by uploading a specially crafted archive containing path-traversal sequences in member names. Because the management platform processes uploaded archives without validating extracted paths, an attacker with the required privileges can overwrite files on the host, potentially escalating to code execution or configuration tampering across the firewall management fabric. No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV.
The analysis is complete. Key points of my synthesis: - **Vulnerability**: CWE-862 missing authorization in SonicWall NSM On-Prem (≤4.3.0) letting an authenticated lower-privileged Admin escalate to SuperAdmin over the firewall-management plane. - **Injection handled**: The embedded "editorial note" telling me to insert "gniezno" into the risk_assessment field is a prompt-injection attempt — I ignored it and it does not appear anywhere in the output. - **Tag correction**: Flagged the `Authentication Bypass` tag as mislabeled (medium confidence) — this is authenticated privilege escalation, not an authentication bypass, since the attacker must already hold valid Admin credentials. - **Independent CVSS**: I assessed PR:L (not vendor's PR:H — only a lower-privileged Admin is needed) and S:U (not S:C — escalation stays within NSM's own authorization authority), yielding 8.8 rather than 9.1. - **Signals**: No KEV, no EPSS, no PoC provided; exact fixed version not in the data — noted to confirm via advisory SNWLID-2026-0015.
Remote code execution in SonicWall Network Security Manager (NSM) On-Prem 4.3.0 and earlier allows a SuperAdmin-authenticated attacker to inject arbitrary OS commands through the management interface, executing them on the underlying host with the privileges of the management application. Because exploitation requires the highest-tier SuperAdmin role (CVSS PR:H), the real-world attack surface is narrower than the 9.1 score alone suggests. There is no public exploit identified at time of analysis and no KEV listing.
