Vulnerability Data

A vulnerability was determined in feiyuchuixue sz-boot-parent up to 1.3.2-beta. Affected by this vulnerability is an unknown functionality of the file /api/admin/sys-user/reset/password/ of the component Password Reset Handler. This manipulation of the argument userId causes use of default password. The…

attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 1.3.3-beta addresses this issue. Patch name: aefaabfd7527188bfba3c8c9eee17c316d094802. It is suggested to upgrade the affected component. The project was informed beforehand and acted very professional: "We have added authorization validation to the password reset interface; now only users with the corresponding permissions are allowed to perform password resets."

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces authorization checks on the password-reset endpoint so that only permitted users may invoke it, eliminating the missing-permission flaw that allowed arbitrary userId-based resets.

AC-6 Least Privilege partial match
prevent

Restricts the password-reset privilege to the minimal set of administrative roles, preventing any user without that explicit right from triggering default-password resets.

IA-5 Authenticator Management partial match
prevent

Requires secure authenticator-management procedures (including controlled password resets) rather than permitting unauthenticated or unrestricted reset operations that produce default passwords.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-01 full match
prevents

Credential management directly requires replacing default passwords with unique, strong credentials.

PR.PS-01 mostly match
prevents

Hardened configuration baselines explicitly prohibit default passwords, covering most of the weakness but not all identity-management aspects.

ID.RA-01 partial match
prevents

Vulnerability scanning will discover default-password instances, enabling remediation, yet does not itself prevent their initial use.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default passwords but do not address the full scope of credential lifecycle.

PR.AA-05 partial match
prevents

Authorization policies assume credentials already exist and are not default; least-privilege helps limit impact but does not prevent defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.17 Authentication information mostly match
prevents

Mandates secure handling and change of authentication secrets, directly addressing default passwords.

A.8.9 Configuration management mostly match
prevents

Configuration management processes typically enforce changing defaults during hardening.

A.8.5 Secure authentication partial match
mitigates

Requires secure authentication mechanisms, which includes replacing or disabling default credentials.

A.8.18 Use of privileged utility programs none match
none

Utility programs often ship with defaults; control requires secure configuration before use.

A.8.2 Privileged access rights none match
none

Privileged accounts must not retain factory passwords, reducing risk of default-credential abuse.
