Vulnerability Data
A Improper Privilege Management vulnerability in SUSE Rancher causes permission changes in Azure AD not to be reflected to users while they are logged in the Rancher UI. This would cause the users to retain their previous permissions in Rancher,…
more
even if they change groups on Azure AD, for example, to a lower privileged group, or are removed from a group, thus retaining their access to Rancher instead of losing it. This issue affects Rancher: from >= 2.6.7 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Mandates lowering or adjusting privileges to match new operational needs, reducing errors in privilege dropping during transfers.
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.
Explicit inclusion of least-privilege policy directly addresses failure to drop privileges before handing control to lower-privileged actors.
Secure-development practices encompass correct privilege-dropping logic, though the control is broader than this single weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
Restricting use of privileged utility programs forces explicit privilege lowering before handing control to unprivileged actors.
Privileged access rights explicitly require least-privilege assignment and timely revocation, directly mitigating failure to drop privileges.
Secure development lifecycle includes privilege management reviews, providing indirect coverage of the weakness.
Secure coding standards can mandate privilege-dropping calls, yet the control is broader than this single weakness.
Information access restriction policies can limit privilege scope but do not specifically address dropping privileges at runtime.
