CVE-2024-34471 — An issue was discovered in HSC Mailinspector 5.2.17-3

Medium CVSS 5.4

An issue was discovered in HSC Mailinspector 5.2.17-3. A Path Traversal vulnerability (resulting in file deletion) exists in the mliRealtimeEmails.php file. The filename parameter in the export HTML functionality does not properly validate the file location, allowing an attacker to read and delete arbitrary files on the server. This was observed when the mliRealtimeEmails.php file itself was read and subsequently deleted, resulting in a 404 error for the file and disruption of email information loading.

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.
