Quick assessment

Affected
Nozomi Networks Guardian
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在凭据管理器（Credentials Manager）功能中，由于对用户权限的校验不足，发现了一个访问控制漏洞。一个拥有受限权限的远程认证用户能够查看可用凭据条目的一个有限子集。虽然实际的凭据值不会直接可见，但该用户仍然可以删除条目或编辑其属性。攻击者如果删除或编辑某个条目，可能会中断依赖该凭据的设备的认证过程；而如果攻击者能够操纵某个条目的配置，则可能间接获取其中的凭据。

Vulnerability Title
Incorrect authorization in Credentials Manager in Guardian/CMC before 26.3.0
Source: CVE Program / CVE List V5
Vulnerability Description
An access control vulnerability was discovered in the Credentials Manager functionality due to insufficient validation of user privileges. A remote authenticated user with limited privileges can view a limited subset of the available entries in the Credentials Manager. The actual credential values are not directly visible, but the user can delete entries or edit their properties. An attacker who deletes or edits an entry can disrupt authentication for dependent devices, and one who manipulates an entry's configuration may be able to indirectly obtain the credentials.
