标题:cups 安全漏洞 (CVE-2024-47176)Description:cups是cups开源的一个类 Unix 操作系统的组合式印刷系统。 cups存在安全漏洞，该漏洞源于cups-browsed绑定到INADDR_ANY:631，导致它信任来自任何来源的任何数据包，并可能导致向攻击者控制的 URL 发出Get-Printer-Attributes IPP 请求。
Description
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.
