news 2025/9/18 1:05:35

漏洞信息

NVD - cve-2023-37461

Metersphere is an opensource testing framework. Files uploaded to Metersphere may define a belongType value with a relative path like ../../../../ which may cause metersphere to attempt to overwrite an existing file in the defined location or to create a new file. Attackers would be limited to overwriting files that the metersphere process has access to. This issue has been addressed in version 2.10.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Debug1：访问Web UI有{"success":false,"message":"401 UNAUTHORIZED \"Not found session, Please Login again.\"","data":null}报错，一定要等待所有容器Up并healthy状态，后再等5min访问Web UI（不要中途切换）。

Debug2：9090端口号占用问题，在docker-compose-prometheus.yml和install.conf修改为9091即可。

# Debug3: Additionally
$ msctl restart gateway
$ msctl restart workstation
$ msctl restart prometheus

漏洞分析

uploadAttachment方法检查了BelongType是否等于ISSUE以及TEST_CASE。如果都不是，就直接在函数saveAttachment中使用BelongType作为文件名的一部分，导致路径穿越。
