Zammad 是一款基于 Web 的开源帮助台/客户支持系统。在版本 7.0.3 和 7.1.1 中，经过身份验证的管理员可以通过集成管理 API 获取明文存储的集成凭据。某些响应并未一致地对敏感字段进行遮蔽处理，导致配置的密钥以明文形式返回，而非预期的遮蔽占位符。LDAP 和 Exchange 集成均受此问题影响。该问题已在版本 7.1.2 中得到修复。

Vulnerability Title
Zammad: Sensitive Information Exposure in Integration Administration API
Source: CVE Program / CVE List V5
Vulnerability Description
Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, an authenticated administrator can obtain stored integration credentials in cleartext through the integration administration API. Certain responses do not consistently mask sensitive fields, so configured secrets can be returned in plain text instead of the expected masked placeholder. Both the LDAP and Exchange integrations are affected. This issue is fixed in version 7.1.2.
