CVE-2023-0862· NVD / CVE Program· CNA ONEKEY

Path Traversal in NetModule NSRW

Noroxi assessment

Priority: Monitor (action score 36/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 2.3% (FIRST EPSS); higher than 83.6% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: NetModule NSRW 4.3.0.119, 4.4.0.118, 4.6.0.105.

Low priority for now. Upgrade to NetModule NSRW 4.3.0.119, 4.4.0.118, 4.6.0.105 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The NetModule NSRW web administration interface is vulnerable to path traversals, which could lead to arbitrary file uploads and deletion. By uploading malicious files to the web root directory, authenticated users could gain remote command execution with elevated privileges. This issue affects NSRW: from 4.3.0.0 before 4.3.0.119, from 4.4.0.0 before 4.4.0.118, from 4.6.0.0 before 4.6.0.105, from 4.7.0.0 before 4.7.0.103.

Weakness class (CWE)

CWE-22 · Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

Fixed

1const file = path.resolve(ROOT, req.query.name);
