Vulnerability Title
Code Injection in Sourcegraph
Vulnerability Description
Sourcegraph is a code search and navigation engine. Sourcegraph prior to version 3.37 is vulnerable to remote code execution in the `gitserver` service. The service acts as a git exec proxy, and fails to properly restrict calling `git config`. This allows an attacker to set the git `core.sshCommand` option, which sets git to use the specified command instead of ssh when they need to connect to a remote system. Exploitation of this vulnerability depends on how Sourcegraph is deployed. An attacker able to make HTTP requests to internal services like gitserver is able to exploit it. This issue is patched in Sourcegraph version 3.37. As a workaround, ensure that requests to gitserver are properly protected.

Vulnerability Title
Sourcegraph 代码注入漏洞
Vulnerability Description
Sourcegraph是美国Sourcegraph公司的一款开源的代码搜索和导航工具。 Sourcegraph 存在代码注入漏洞，该漏洞允许攻击者设置git的core.sshCommand选项，该选项将git设置为在需要连接到远程系统时使用指定的命令而不是ssh。此漏洞的利用取决于 Sourcegraph 的部署方式。能够向 gitserver 等内部服务发出 HTTP 请求的攻击者能够利用它。
