Vulnerability Title
Fluentd: Remote Code Execution (RCE) via Arbitrary File Write in `${tag}` Placeholder
Vulnerability Description
Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Prior to 1.19.3, Fluentd allows dynamically constructing file paths using the ${tag} placeholder, and insufficient validation of ${tag} in file configurations such as the path parameter of the out_file plugin allows attackers sending untrusted tags containing path traversal characters to write or overwrite arbitrary files and potentially achieve remote code execution. This issue is fixed in version 1.19.3.

Vulnerability Title
Fluentd 路径遍历漏洞
Vulnerability Description
Fluentd是Fluentd团队开源的一个开源日志收集器。从各种数据源收集事件,并将其写入文件、RDBMS、NoSQL、IaaS、SaaS、Hadoop等。 Fluentd 1.19.3之前版本存在路径遍历漏洞,该漏洞源于对out_file插件路径参数中的${tag}占位符验证不足,允许攻击者发送包含路径遍历字符的不可信标签,从而写入或覆盖任意文件,并可能实现远程代码执行。
