Vulnerability Title
Freeipa: ipa: freeipa: trust-fetch-domains uses trust-read aci to gate a privileged ad trust refresh, allowing unauthorized ldap writes
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied server and credentials, resulting in unauthorized, attacker-controlled modification of trusted-domain and ID-range identity data in the IPA LDAP directory.

Source: CVE Program / CVE List V5
Vulnerability Title
FreeIPA 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
FreeIPA是FreeIPA组织开源的一款身份认证与权限管理产品。 FreeIPA存在授权问题漏洞，该漏洞源于trust-fetch-domains命令受信任对象上的只读权限而非信任管理权限控制，可能导致经过身份验证的非特权IPA用户使用攻击者提供的服务器和凭据触发特权Active Directory信任刷新，导致IPA LDAP目录中受信任域和ID范围身份数据被未授权修改。
