Title

Cloud Foundry UAA SCIM权限提升漏洞

Description

UAA是Cloud Foundry中使用的多租户身份管理服务，也可作为独立的OAuth2服务器使用。 Cloud Foundry UAA 74.1.0之前版本存在SCIM盲注权限提升漏洞。该漏洞源于UAA允许直接查询外部输入。具有'client.write'和'groups.update'权限的远程攻击者可利用该漏洞通过构建SCIM查询获取信息，从而可实现权限提升，从而可越权控制UAA范围。

CVE-2019-11278 (GCVE-0-2019-11278)

Vulnerability from cvelistv5 – Published: 2019-09-26 21:11 – Updated: 2024-09-16 23:51

Title

Privilege Escalation via Blind SCIM Injection in UAA

Summary

CF UAA versions prior to 74.1.0, allow external input to be directly queried against. A remote malicious user with 'client.write' and 'groups.update' can craft a SCIM query, which leaks information that allows an escalation of privileges, ultimately allowing the malicious user to gain control of UAA scopes they should not have.

Severity

8.7 (High)
