公告ID:KYSA-202104-1251 公告摘要:samba安全漏洞 安全等级:Important 发布日期:2021年04月08日 影响CVE:CVE-2017-7494、CVE-2019-10218、CVE-2019-14907

详细介绍

1. 修复的CVE

·CVE-2017-7494

描述:在Samba中发现远程代码执行缺陷。通过身份验证的恶意samba客户端具有对samba共享的写访问权限,可以使用此漏洞以根用户身份执行任意代码。

·CVE-2019-10218

描述:在客户机提供的samba服务器路径中发现了恶意漏洞。这将允许客户端访问SMB网络路径名之外的文件和文件夹。攻击者可以利用此漏洞使用客户端用户的权限在当前工作目录之外创建文件.

·CVE-2019-14907

描述:所有samba版本4.9.18之前的4.9.x版本、4.10.12之前的4.10.x版本和4.11.5之前的4.11.x版本都存在一个问题,如果设置为";log level=3";(或更高版本),则在字符转换失败后,从客户端获取的字符串将被打印。在NTLMSSP身份验证交换期间可以提供这样的字符串。特别是在sambaaddc中,这可能会导致一个长期存在的进程(例如RPC服务器)终止。(在文件服务器的情况下,最有可能的目标smbd按每个客户端的进程运行,因此崩溃是无害的)。
