CVE intelligence and bounded remediation
CVE-2022-24688 — An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5
An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5. The Touch settings allow unrestricted file upload (and consequently Remote Code Execution) via PDF upload with PHP content and a .php extension. The attacker must hijack or obtain privileged user access to the Parameters page in order to exploit this issue. (That can be easily achieved by exploiting the Broken Access Control with further Brute-force attack or SQL Injection.) The uploaded file is stored within the database and copied to the sync web folder if the attacker visits a certain .php?action= page.

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.
