低危 递归地复制存储库时的任意代码执行
CVE编号
CVE-2018-11235利用情况
POC 已公开补丁情况
官方补丁披露时间
2018-05-30漏洞描述
在2.13.7之前的Git，2.14.4之前的2.14.x，2.15之前的2.15.x，2.16之前的2.16.x和2.17之前的2.17.x，可能会发生远程代码执行。使用精心设计的.gitmodules文件，恶意项目可以在运行“git clone --recurse-submodules”的计算机上执行任意脚本，因为子模块“names”是从此文件中获取的，然后附加到$ GIT_DIR / modules，目录遍历名称中带有“../”。最后，执行子模块的post-checkout hooks，绕过未从远程服务器获取hooks的预期设计。解决建议
