CVE-2023-29048 — Open-Xchange Ox App Suite security vulnerability

High CVSS 8.8

A component for parsing OXMF templates could be abused to execute arbitrary system commands that would be executed as the non-privileged runtime user. Users and attackers could run system commands with limited privilege to gain unauthorized access to confidential information and potentially violate integrity by modifying resources. The template engine has been reconfigured to deny execution of harmful commands on a system level. No publicly available exploits are known.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
