CVE-2023-24603
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 · uneditedOX App Suite before backend 7.10.6-rev37 does not check size limits when downloading, e.g., potentially allowing a crafted iCal feed to provide an unlimited amount of data.
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 confidenceOX App Suite versions prior to backend 7.10.6-rev37 fail to enforce size constraints when processing downloads, specifically when handling iCal feeds. This allows an attacker to supply a crafted iCal feed that can transmit unbounded data volumes to the vulnerable system, potentially exhausting server resources and causing denial of service.

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 backend versionLocate the installed OX App Suite backend version in the system configuration or package management system, typically found in the server's software inventory or about panelAffected if The installed version is less than 7.10.6-rev37 (including version 7.10.6 exactly)
-
Confirm iCal feed processing is enabledVerify whether the system is configured to process or import iCal feeds, as this is the specific attack vector for this vulnerabilityAffected if iCal feed processing functionality is active or configurable on the server
-
Check download size limit configurationsInspect the download and feed import settings for any configured size limits or validation constraints on incoming dataAffected if No size limits are enforced on download operations or iCal feed imports
The environment is affected if the OX App Suite backend version is 7.10.6 or any version prior to 7.10.6-rev37, and iCal feed processing is enabled without enforced size constraints.
Generated from the published advisory. Verify against your own configuration.
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
Upgrade OX App Suite backend to version 7.10.6-rev37 or later, which implements proper size limit validation on download operations. Implement input validation and size checks on external data feeds as a defense-in-depth measure.
OX App Suite backend version 7.10.6-rev37 or later
- 1. Identify current OX App Suite backend version by checking the system configuration or running version query command
- 2. Plan maintenance window as upgrade may require service restart
- 3. Upgrade OX App Suite backend to version 7.10.6-rev37 or later
- 4. After upgrade, verify size limit checks are now enforced for iCal downloads
- 5. Test iCal feed functionality to confirm normal operation is maintained
