Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

SuiteCRM 是一款开源的、面向企业级的客户关系管理（CRM）软件应用。在 7.15.2 和 8.10.2 版本之前，的密码授权（password-grant）端点会对“无效用户名”和“无效密码”返回不同的错误消息。未认证的远程攻击者可利用这些响应差异来枚举有效的 CRM 用户名，并对已确认存在的账户实施密码喷洒、凭证填充、暴力破解或社会工程学攻击。该问题已在 7.15.2 和 8.10.2 版本中修复。

Vulnerability Title

SuiteCRM: V8 OAuth2 Username Enumeration

Source: CVE Program / CVE List V5

Vulnerability Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the /legacy/Api/V8/OAuth2 password-grant endpoint returns distinct error messages for an invalid username and an invalid password. An unauthenticated remote attacker can use those response differences to enumerate valid CRM usernames and target confirmed accounts with password spraying, credential stuffing, brute-force, or social-engineering attacks. This issue is fixed in versions 7.15.2 and 8.10.2.
