CVE-2025-59044 (CNNVD-202509-1124)
中文标题:
Himmelblau 安全漏洞
英文标题:
Himmelblau vulnerable to GID collision via group name-derived mapping (privilege escalation)
漏洞描述
中文描述:
Himmelblau是Himmelblau开源的一个 Azure Entra ID 身份验证模块。 Himmelblau 0.9.0至0.9.22版本存在安全漏洞,该漏洞源于从组显示名称派生数字GID,可能导致授权绕过。
英文描述:
Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. Himmelblau 0.9.x derives numeric GIDs for Entra ID groups from the group display name when himmelblau.conf `id_attr_map = name` (the default configuration). Because Microsoft Entra ID allows multiple groups with the same `displayName` (including end-user–created personal/O365 groups, depending on tenant policy), distinct directory groups can collapse to the same numeric GID on Linux. This issue only applies to Himmelblau versions 0.9.0 through 0.9.22. Any resource or service on a Himmelblau-joined host that enforces authorization by numeric GID (files/dirs, etc.) can be unintentionally accessible to a user who creates or joins a different Entra/O365 group that happens to share the same `displayName` as a privileged security group. Users should upgrade to 0.9.23, or 1.0.0 or later, to receive a patch. Group to GID mapping now uses Entra ID object IDs (GUIDs) and does not collide on same-name groups. As a workaround, use tenant policy hardening to restrict arbitrary group creation until all hosts are patched.
