CVE-2023-26453
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 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 confidenceThe imageconverter service has a SQL injection vulnerability in its image caching functionality. Attackers could embed malicious SQL queries in image cache requests that would be executed unchecked against the database. The vulnerability requires network access to the imageconverter service (not exposed publicly by default) and allows arbitrary SQL execution 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 the installed Appsuite versionCheck the installed version of Open Xchange Appsuite by examining the package manager, OX configuration files, or the oxreport output. Common locations include /opt/open-xchange/etc/Version or querying the OX service directly.Affected if The installed version is 7.10.6 or any version below 7.10.6 (versions < 7.10.6)
-
Determine if imageconverter service is installed and runningCheck if the imageconverter service is enabled by reviewing the service configuration files or process list. Look for the imageconverter process or service definition in the OX deployment.Affected if The imageconverter service is installed and running on the system
-
Verify network exposure of imageconverter serviceReview network configuration and firewall rules to determine if the imageconverter service port is accessible from untrusted networks. Check configuration files for binding addresses.Affected if The imageconverter service is accessible from networks beyond the intended administrative or adjacent network segments
-
Inspect database user privilegesReview the database configuration used by the imageconverter service to identify the database user account it employs and its privilege level.Affected if The imageconverter service connects to the database with a user account that has elevated privileges beyond read-only access
-
Review application logs for suspicious SQL patternsExamine imageconverter and database logs for unusual SQL syntax, UNION statements, OR conditions, or other SQL injection patterns in cache-related requests.Affected if Logs contain SQL query patterns that appear malformed or contain unexpected SQL syntax in image cache requests
A user is affected if they run Open Xchange Appsuite version 7.10.6 or below with the imageconverter service enabled and network-accessible, particularly if the service uses a database account with elevated privileges.

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
Ensure the imageconverter service is updated to the patched version. Verify the SQL injection protection is active by reviewing logs for blocked injection attempts. Maintain network segmentation to limit access to adjacent networks only.
Open Xchange Appsuite 7.10.6 or later stable release
- Identify the current installed version of Open Xchange Appsuite
- Upgrade to version 7.10.6 or later (7.10.6-revision or newer stable release)
- Verify the upgrade by checking that the image caching API requests are now properly validated
- Monitor logs for any attempts to circumvent the content validation checks
