CVE intelligence and bounded remediation

CVE-2023-34096 — Thruk is a multibackend monitoring webinterface which currently supports Naemon, Icinga, Shinken and Nagios as backends

High CVSS 8.8

Thruk is a multibackend monitoring webinterface which currently supports Naemon, Icinga, Shinken and Nagios as backends. In versions 3.06 and prior, the file `panorama.pm` is vulnerable to a Path Traversal vulnerability which allows an attacker to upload a file to any folder which has write permissions on the affected system. The parameter location is not filtered, validated or sanitized and it accepts any kind of characters. For a path traversal attack, the only characters required were the dot (`.`) and the slash (`/`). A fix is available in version 3.06.2.

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.
