CVE intelligence and bounded remediation
CVE-2024-43011 — An arbitrary file deletion vulnerability exists in the admin/del.php file at line 62 in ZZCMS 2023 and earlier
An arbitrary file deletion vulnerability exists in the admin/del.php file at line 62 in ZZCMS 2023 and earlier. Due to insufficient validation and sanitization of user input for file paths, an attacker can exploit this vulnerability by using directory traversal techniques to delete arbitrary files on the server. This can lead to the deletion of critical files, potentially disrupting the normal operation of the system.

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.
