CVE intelligence and bounded remediation
CVE-2019-17224 — Compal Ch7465Lg Firmware security vulnerability
Medium
CVSS 5.3
The web interface of the Compal Broadband CH7465LG modem (version CH7465LG-NCIP-6.12.18.25-2p6-NOSH) is vulnerable to a /%2f/ path traversal attack, which can be exploited in order to test for the existence of a file pathname outside of the web root directory. If a file exists but is not part of the product, there is a 404 error. If a file does not exist, there is a 302 redirect to index.html.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
