CVE-2023-21418 — Axis Axis Os security vulnerability

High CVSS 7.1

Sandro Poppi, member of the AXIS OS Bug Bounty Program, has found that the VAPIX API irissetup.cgi was vulnerable to path traversal attacks that allows for file deletion. This flaw can only be exploited after authenticating with an operator- or administrator-privileged service account. The impact of exploiting this vulnerability is lower with operator service accounts and limited to non-system files compared to administrator-privileges. Axis has released patched AXIS OS versions for the highlighted flaw. Please refer to the Axis security advisory for more information and solution.

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.
