Quick assessment

Affected
ctfer-io monitoring
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.

Monitoring是CTFer.io开源的一个监控数据的收集与处理组件。 Monitoring 0.2.2之前版本存在路径遍历漏洞，该漏洞源于sanitizeArchivePath函数存在路径遍历，可能导致任意文件写入和远程代码执行。

Vulnerability Title
Monitoring is vulnerable to Archive Slip due to missing checks in sanitization
Source: CVE Program / CVE List V5
Vulnerability Description
The CTFer.io Monitoring component is in charge of the collection, process and storage of various signals (i.e. logs, metrics and distributed traces). In versions prior to 0.2.2, the sanitizeArchivePath function in pkg/extract/extract.go (lines 248–254) is vulnerable to Path Traversal due to a missing trailing path separator in the strings.HasPrefix check. The extractor allows arbitrary file writes (e.g., overwriting shell configs, SSH keys, kubeconfig, or crontabs), enabling RCE and persistent backdoors. The attack surface is further amplified by the default ReadWriteMany PVC access mode, which lets any pod in the cluster inject a malicious payload. This issue has been fixed in version 0.2.2.
