Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 ansible-runner 中发现了一个漏洞。 函数负责接收并解压通过 ansible-runner transmit/worker 协议在 worker 端传输的流式 zip 归档文件。该函数在从归档内容中重建符号链接时，未对链接目标进行验证；同时，它对源自归档成员名称的未经净化的文件系统路径执行了 和 操作。如果 worker 处理了一个由攻击者影响输入所构造的恶意归档，则可能在预期目标目录之外创建文件、创建符号链接或修改权限，进而可能被利用以实现代码执行。

Vulnerability Title
Ansible-runner: ansible-runner: path traversal and symlink escape in unstream_dir() allows file write outside the target directory
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in ansible-runner. The unstream_dir() function, which receives and extracts a streamed zip archive on the worker side of the ansible-runner transmit/worker protocol, re-creates symbolic links from archive content without validating the link target and applies chmod() and utime() to an unsanitized filesystem path derived from the archive member name. A crafted archive processed by a worker that consumes attacker-influenced input can create files, create symbolic links, or change permissions outside the intended target directory, which can be leveraged toward code execution.
