CVE-2025-54999 Details
Description
OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 0.1.0 through 2.3.1, when using OpenBao's userpass auth method, user enumeration was possible due to timing difference between non-existent users and users with stored credentials. This is independent of whether the supplied credentials were valid for the given user. This issue was fixed in version 2.3.2. To work around this issue, users may use another auth method or apply rate limiting quotas to limit the number of requests in a period of time: https://openbao.org/api-docs/system/rate-limit-quotas/.
A user enumeration vulnerability has been identified in OpenBao versions 0.1.0 prior to 2.3.1, specifically within the userpass authentication method. This vulnerability arises from a timing discrepancy that allows for the differentiation between non-existent users and those with stored credentials, regardless of the validity of the supplied credentials. The issue has been addressed in version 2.3.2.
Users can upgrade to OpenBao version 2.3.2, which addresses this vulnerability. Alternatively, rate limiting quotas can be applied to reduce the number of authentication requests within a given timeframe.
