Vulnerability from cnvd - Published: 2021-01-22

Title

Theonedev OneDev目录遍历漏洞

Description

Theonedev Onedev是Theonedev团队的一个基于JAVA的多合一DevOps平台。该平台支持容器构建、编排、CI、Git管理、团队协作等功能，帮助开发者构建一个简单、功能强大的开发平台。 Theonedev Onedev 4.0.3之前版本存在安全漏洞，KubernetesResource REST端点使用TarUtils从请求主体中卸载用户控制的数据。TarUtils是一种利用apachecommons压缩的自定义库方法。在untar过程中，无任何检查可以防止未暂存的文件遍历文件系统并覆盖现有文件。目前没有详细漏洞细节提供。

CVE-2021-21251 (GCVE-0-2021-21251)

Vulnerability from cvelistv5 – Published: 2021-01-15 20:10 – Updated: 2024-08-03 18:09

Summary

OneDev is an all-in-one devops platform. In OneDev before version 4.0.3 there is a critical "zip slip" vulnerability. This issue may lead to arbitrary file write. The KubernetesResource REST endpoint untars user controlled data from the request body using TarUtils. TarUtils is a custom library method leveraging Apache Commons Compress. During the untar process, there are no checks in place to prevent an untarred file from traversing the file system and overriding an existing file. For a successful exploitation, the attacker requires a valid __JobToken__ which may not be possible to get without using any of the other reported vulnerabilities. But this should be considered a vulnerability in `io.onedev.commons.utils.TarUtils` since it lives in a different artifact and can affect other projects using it. This issue was addressed in 4.0.3 by validating paths in tar archive to only allow them to be in specified folder when extracted.
