CVE-2023-26452
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 · uneditedRequests to cache an image and return its metadata could be abused to include SQL queries that would be executed unchecked. Exploiting this vulnerability requires at least access to adjacent networks of the imageconverter service, which is not exposed to public networks by default. Arbitrary SQL statements could be executed in the context of the services database user account. API requests are now properly checked for valid content and attempts to circumvent this check are being logged as error. 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 · high confidenceSQL injection vulnerability in the imageconverter service allows attackers to inject arbitrary SQL queries through API requests when caching images and retrieving metadata. The flaw stems from insufficient input validation on API endpoints, enabling SQL statements to be executed unchecked in the context of the service's database user account.

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 Open Xchange Appsuite versionCheck the installed version of Open Xchange Appsuite by querying the package manager or examining the application metadata. Common methods include: rpm -q ox-se or dpkg -l | grep ox, or checking the /opt/open-xchange/version file if it exists.Affected if The installed version is lower than 7.10.6 or equals exactly 7.10.6
-
Confirm imageconverter service is activeDetermine if the imageconverter service is enabled and running. This may involve checking process lists (ps aux | grep imageconverter), systemd service status (systemctl status imageconverter), or reviewing the service configuration in the Appsuite admin panel.Affected if The imageconverter service is running and accessible to untrusted network sources
-
Identify exposed API endpoints for image operationsReview API documentation or network configuration to locate endpoints that handle image caching and metadata retrieval. Check the OX Appsuite configuration files (e.g., imageconverter.properties or converter.yml) for endpoint definitions and their exposure settings.Affected if API endpoints for image caching or metadata retrieval are exposed to untrusted users or networks without additional authentication layers
-
Examine application logs for SQL injection indicatorsSearch application and database logs for unusual SQL syntax patterns, error messages containing SQL keywords (SELECT, UNION, DROP, etc.) in request parameters, or repeated database errors originating from imageconverter requests. Log locations typically include /var/log/open-xchange/ or the configured log directory.Affected if Logs contain SQL injection attempt signatures or unexpected SQL errors correlated with image API requests
-
Review database user permissions for imageconverterInspect the database user account used by the imageconverter service to determine if it has elevated privileges beyond what is necessary for its function (e.g., DROP, ALTER, or administrative permissions). Connect to the database as an administrator and run: SELECT user, host, privileges FROM mysql.user WHERE user LIKE '%image%' or similar for your database system.Affected if The imageconverter database user has permissions beyond SELECT, INSERT, UPDATE, and DELETE on its designated schema
You are affected if Open Xchange Appsuite version is 7.10.6 or below, the imageconverter service is active, and its image caching/metadata API endpoints are accessible without proper input validation safeguards.

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 · scoped7.10.6
Verify that all API endpoints handling image caching and metadata retrieval now properly validate input and reject malicious SQL injection attempts. Ensure the implemented input validation fix covers all entry points and that logging of bypass attempts is active and monitored.
Open Xchange Appsuite 7.10.6 or later (ensure latest available stable release)
- 1. Upgrade Open Xchange Appsuite to version 7.10.6 or later (the documentation indicates API requests are now properly checked in fixed releases)
- 2. Verify the upgrade by testing image cache and metadata retrieval functionality
- 3. Ensure the imageconverter service remains network-isolated and not exposed to public networks as per default configuration
- 4. Review logs for any attempts to circumvent the content validation checks
