CVE-2023-5607 — Trellix Application And Change Control security vulnerability

High CVSS 8.4

An improper limitation of a path name to a restricted directory (path traversal) vulnerability in the TACC ePO extension, for on-premises ePO servers, prior to version 8.4.0 could lead to an authorised administrator attacker executing arbitrary code through uploading a specially crafted GTI reputation file. The attacker would need the appropriate privileges to access the relevant section of the User Interface. The import logic has been updated to restrict file types and content.

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.
