AI-suggested
European organizations should immediately verify their CUPS versions and upgrade to version 2.4.13 or later, where the authentication bypass is fixed. For environments where immediate patching is not feasible, administrators should review and restrict AuthType configurations to Basic only, if compatible with operational requirements, to avoid triggering the vulnerability. Network segmentation and access controls should be enforced to limit local network access to printing servers, reducing the attack surface. Monitoring and logging of printing service access should be enhanced to detect unusual or unauthorized activities. Additionally, organizations should implement strict user access policies and consider deploying host-based intrusion detection systems to identify exploitation attempts. Regular vulnerability scanning and configuration audits focusing on CUPS and related services are recommended to ensure compliance and early detection of vulnerable instances.
Description
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass. Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the issue.
