CVE-2026-14361

CVE-2026-14361 Consul Template 的 writeToFile 辅助函数直接打开操作者提供的目标路径，并跟随被链接的路径组件，从而使渲染输出能够逃逸预期目录并覆盖已存在的文件。 简介 我在审查 HashiCorp Consul Template 时发现了这个问题，当时脑海中有一个直接的文件系统安全问题： 如果writeToFile 收到的路径看似位于预期目录之内，它是否会验证文件系统实际将数据写入何处？ 在本例中，答案是否定的。 writeToFile 模板辅助函数通过 os.Create 或 os.OpenFile 直接打开用户提供的最终路径。...

golang: Go os.Root: Symlink following vulnerability allows directory traversal

A flaw was found in the os.Root functionality of Go on Unix systems. This vulnerability allows an attacker to bypass intended directory restrictions by crafting a path that ends with a symbolic link and a trailing slash. When a file is opened in os.Root with such a path, the symbolic link is...

subpath-exploit

通过 CVE-2017-1002101 实现 Kubernetes 逃逸示例 描述 在了解到这个问题并参考此指南后，我想进一步探索。该仓库包含几个 Pod 部署和辅助 Shell 脚本，以最简单的方式演示了攻击机制，使 Kubernetes 管理员和运维人员能够充分理解其严重性和潜在风险。您必须是已认证用户，或者能够在创建 Pod 时控制其 spec/template，因此这种逃逸不太可能以匿名方式发生，除非与其他攻击（如这个）结合使用。 快速解释 当 Kubelet 挂载卷/密钥/配置映射等时，它会错误地跟随卷内部的符号链接，访问到本应限制范围之外的位置。由于 Kubelet 以 ro...

rsync: rsync: Local Privilege Escalation via Symlink Following

A symlink-following vulnerability in rsync allows local attackers to redirect predictable output paths to arbitrary filesystem locations. When rsync runs with elevated privileges such as setuid or a privileged daemon, this enables arbitrary file overwrites and local privilege escalation...

rsync: rsync: Arbitrary File Read via Symlink Following

A flaw was found in rsync. A local attacker with low privileges can exploit a symlink following vulnerability in the handling of input configuration files, such as those specified by --files-from or --password-file. This allows the attacker to read arbitrary files accessible to the rsync daemon...

Hugo is a static site generator. In versions after v0.123.0 and before v0.165.0, symlinks in parent directories were not dropped during direct resource lookups, allowing path confinement to be bypassed. An attacker who can place — or who convinces a site author to place — a symlink inside a mount...
