SkyWalking 漏洞列表

SkyWalking SQL Injection fofa: app="APACHE-Skywalking"

When using H2/MySQL/TiDB as Apache SkyWalking storage and a metadata query through GraphQL protocol, there is a SQL injection vulnerability which allows access to unexpected data. Apache SkyWalking 6.0.0 to 6.6.0, 7.0.0 H2/MySQL/TiDB storage implementations don't use the appropriate way to set SQL parameters.

Apache SkyWalking基于log4J组件的远程命令执行漏洞。

Skywalking历史上存在两次sql注入漏洞，CVE-2020-9483、CVE-2020-13921。经过源码分析，发现两次sql注入漏洞修复并不完善，仍存在一处sql注入漏洞。(该请求无页面入口，需要根据graphql配置文件手动进行请求构造，或许这就是官方遗漏该注入点的原因)Skywalking默认配置下使用的数据库为h2，且使用sa权限启动。于是我们可以先利用任意文件写入函数在classpath中写一个恶意类，然后再使用LINK_SCHEMA函数来加载这个恶意类，实现远程代码执行。
