GNU Bash 远程代码执行漏洞
(CVE-2014-6271)
描述：GNU Bash是美国软件开发者布莱恩-福克斯（Brian J. Fox）为GNU计划而编写的一个Shell（命令语言解释器），它运行于类Unix操作系统中（Linux系统的默认Shell），并能够从标准输入设备或文件中读取、执行命令，同时也结合了一部分ksh和csh的特点。 GNU Bash 4.3及之前版本中存在安全漏洞，该漏洞源于程序没有正确处理环境变量值内的函数定义。远程攻击者可借助特制的环境变量利用该漏洞执行任意代码。以下产品和模块可能会被利用：OpenSSH sshd中的ForceComman
描述
A PoC exploit for CVE-2014-6271 - Shellshock
介绍
# CVE-2014-6271 - Shellshock 💣
Shellshock is a critical vulnerability in the GNU Bash shell. It affects versions through 4.3 and allows remote attackers to execute arbitrary code. This exploit occurs due to how Bash processes trailing strings after function definitions in the values of environment variables.
## 🔍 Detailed Explanation
The Shellshock vulnerability allows an attacker to inject and execute code via specially crafted environment variables. These variables can be set through various vectors, such as:
- The **ForceCommand** feature in OpenSSH's `sshd`
- The **mod_cgi** and **mod_cgid** modules in the Apache HTTP Server
- Scripts executed by unspecified DHCP clients
These scenarios involve setting environment variables across a privilege boundary, making it possible for attackers to execute arbitrary code with elevated privileges.
