CVE-2024-47176 PoC — cups 安全漏洞

Description

Unix CUPS打印系统 远程代码执行漏洞

介绍

# CVE-2024-47176
CUPS（Common UNIX Printing System，通用Unix打印系统）是一个打印系统，它主要是使用 IPP（Internet Printing Protocol）等协议来管理打印工作及队列。

2024年9月27日，互联网上披露 Unix CUPS 远程代码执行详情，利用链涉及多个CVE（CVE-2024-47176/CVE-2024-47076/CVE-2024-47175/CVE-2024-47177等）。当cups-browsed进程监听（默认631端口）接收UDP数据包时，攻击者可构造恶意请求，在无需认证的情况下可能在受害者机器上执行任意命令，控制服务器。漏洞实际是否可利用和触发需要依赖具体环境（例如存在打印任务等）
