Detailsinfo

A vulnerability was found in OpenBao (version now known). It has been declared as problematic. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a whitespace vulnerability. The CWE definition for the vulnerability is CWE-156. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as whitespace when they are sent to a downstream component. As an impact it is known to affect confidentiality. The summary by CVE is:

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, OpenBao's TOTP secrets engine could accept valid codes multiple times rather than strictly-once. This was caused by unexpected normalization in the underlying TOTP library. To work around, ensure that all codes are first normalized before submitting to the OpenBao endpoint. TOTP code verification is a privileged action; only trusted systems should be verifying codes.
