CVE-2024-23186
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedE-Mail containing malicious display-name information could trigger client-side script execution when using specific mobile devices. Attackers could perform malicious API requests or extract information from the users account. Please deploy the provided updates and patch releases. We now use safer methods of handling external content when embedding displayname information to the web interface. No publicly available exploits are known.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a stored Cross-Site Scripting (XSS) vulnerability in the email web interface where malicious JavaScript can be embedded in the email sender's display-name field. When rendered on specific mobile devices, the unsanitized display-name executes client-side scripts, allowing attackers to perform unauthorized API requests and extract user account information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Ox App Suite versionRun command: cat /opt/open-xchange/etc/version.properties or check package manager: dpkg -l | grep open-xchange or rpm -qa | grep open-xchangeAffected if Version is lower than 8.22 (e.g., 8.21.x, 8.20.x, etc.)
-
Confirm web interface is deployedCheck if the Ox App Suite web portal is accessible by visiting the application's login page URL (typically port 80/443) and verify the ox app suite frontend is servingAffected if Web interface is exposed and running an affected version below 8.22
-
Verify email module is enabledCheck Ox App Suite configuration file /opt/open-xchange/etc/oxappsuite.conf or inspect active plugins: listbundles | grep -i mailAffected if Email module is enabled and running on an affected version
Your environment is affected if Ox App Suite version is below 8.22 and the email web interface is accessible with the mail module enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped8.22
Deploy the vendor-provided patch releases immediately. Ensure all email display-name content is properly sanitized before rendering in the web interface, using safe encoding methods for external content.
8.22
- Check current Ox App Suite version using the admin dashboard or command-line tools
- Schedule a maintenance window for the upgrade process
- Create a complete backup of the current Ox App Suite installation and database
- Upgrade Ox App Suite to version 8.22 or later using the official upgrade procedures
- After upgrade, verify that the display-name handling now uses safer methods for embedding content in the web interface
- Test that legitimate e-mail display names render correctly without script execution
