Sudo Local Privilege Escalation Vulnerability

漏洞信息

漏洞名称： Sudo Local Privilege Escalation Vulnerability

漏洞编号：

• CVE： CVE-2025-32463

漏洞类型： 权限提升

漏洞等级： 高危

漏洞描述： ### 受影响产品
Sudo是一个在Unix和Linux操作系统中广泛使用的程序，允许用户以其他用户（通常是超级用户或root）的安全权限运行程序。它是系统管理员和普通用户日常操作中不可或缺的工具，尤其在多用户环境中。由于其广泛的使用和高度信任的特性，Sudo中的漏洞可能会对系统安全造成严重影响。

漏洞说明

CVE-2025-32463是一个本地权限提升漏洞，源于Sudo命令中对用户输入的不当验证。攻击者可以利用此漏洞在受影响的系统上执行具有root权限的命令。这种类型的漏洞通常由于软件在处理用户提供的输入时未能充分验证或清理输入，从而导致安全边界被绕过。

影响分析

此漏洞允许本地用户通过特定的输入序列绕过预期的权限限制，从而获得root权限。这意味着攻击者可以在系统上执行任意命令，包括安装程序、查看、更改或删除数据，或创建具有完全用户权限的新账户。由于这是一个本地漏洞，攻击者需要有一定的系统访问权限才能利用它。然而，一旦利用成功，其影响是极其严重的，可能导致完全的系统妥协。此外，由于Sudo的普遍存在，这个漏洞的影响范围非常广泛，尤其是在未及时打补丁的系统上。
