CUPS is a standards-based, open-source printing system, and cups-browsed contains network printing functionality including, but not limited to, auto-discovering print services and shared printers. cups-browsed binds to INADDR_ANY:631, causing it to trust any packet from any source, and can cause the Get-Printer-Attributes IPP request to an attacker controlled URL.

Due to the service binding to *:631 ( INADDR_ANY ), multiple bugs in cups-browsed can be exploited in sequence to introduce a malicious printer to the system. This chain of exploits ultimately enables an attacker to execute arbitrary commands remotely on the target machine without authentication when a print job is started. This poses a significant security risk over the network. Notably, this vulnerability is particularly concerning as it can be exploited from the public internet, potentially exposing a vast number of systems to remote attacks if their CUPS services are enabled.
