CVE-2023-28102— discordrb操作系统命令注入漏洞

Command injection in discordrb

discordrb is an implementation of the Discord API using Ruby. In discordrb before commit `91e13043ffa` the `encoder.rb` file unsafely constructs a shell string using the file parameter, which can potentially leave clients of discordrb vulnerable to command injection. The library is not directly exploitable: the exploit requires that some client of the library calls the vulnerable method with user input. However, if unsafe input reaches the library method, then an attacker can execute arbitrary shell commands on the host machine. Full impact will depend on the permissions of the process running the `discordrb` library and will likely not be total system access. This issue has been addressed in code, but a new release of the `discordrb` gem has not been uploaded to rubygems. This issue is also tracked as `GHSL-2022-094`.

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

discordrb操作系统命令注入漏洞

discordrb是Shard Lab个人开发者的使用Ruby实现Discord API的存储库。 discordrb存在操作系统命令注入漏洞，该漏洞源于encoder.rb文件使用file参数不安全地构造了一个shell字符串，导致客户端容易受到命令注入攻击。
