# Atlassian Jira ViewUserHover.jspa 用户信息泄露漏洞 CVE-2020-14181
|
||
|
||
## 漏洞描述
|
||
|
||
Jira存在一个未授权访问漏洞，未授权的用户可以通过一个api接口直接查询到某用户名的存在情况，该接口不同于CVE-2019-8446和CVE-2019-3403的接口，是一个新的接口。如果Jira暴露在公网中，未授权用户就可以直接访问该接口爆破出潜在的用户名。
|
||
|
||
## 漏洞影响
|
||
|
||
```
|
||
Atlassian Jira < 7.13.6
|
||
Atlassian Jira 8.0.0 - 8.5.7
|
||
Atlassian Jira 8.6.0 - 8.12.0
|
||
```
|
||
|
||
## FOFA
|
||
|
||
```
|
||
app="Jira"
|
||
```
|
||
|
||
## 漏洞复现
|
||
|
||
打开主界面，注意标识中的 Jira版本是否在影响中
|
||
|
||
|
||
|
||
|
||
|
||
使用POC对用户名是否存在进行验证
|
||
|
||
```
|
||
/secure/ViewUserHover.jspa?username=admin
|
||
```
|
||
|
||
用户名如果不存在会返回
|
||
|
||
|
||
|
||
存在的用户名会返回
|
||
|
||
|
||
|
||
不存在漏洞会返回
|
||
|
||
|
||
|
||
## 漏洞POC
|
||
|
||
POC只用于探测是否存在漏洞
