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.

MITRE ATT&CK Enterprise Techniques

T1548.001 Setuid and Setgid Privilege Escalation
An adversary may abuse configurations where an application has the setuid or setgid bits set in order to get code running in a different (and possibly more privileged) user’s context.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1134 Access Token Manipulation Stealth
Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls.
T1548 Abuse Elevation Control Mechanism Privilege Escalation
Adversaries may circumvent mechanisms designed to control privilege elevation to gain higher-level permissions.

Mitigating Controls

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.

addresses: CWE-271

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.

PR.AA-05 mostly match
prevents

Explicit inclusion of least-privilege policy directly addresses failure to drop privileges before handing control to lower-privileged actors.

PR.PS-06 partial match
prevents

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.

degrades

Restricting use of privileged utility programs forces explicit privilege lowering before handing control to unprivileged actors.

degrades

Privileged access rights explicitly require least-privilege assignment and timely revocation, directly mitigating failure to drop privileges.

prevents

Secure development lifecycle includes privilege management reviews, providing indirect coverage of the weakness.

prevents

Secure coding standards can mandate privilege-dropping calls, yet the control is broader than this single weakness.

mitigates

Information access restriction policies can limit privilege scope but do not specifically address dropping privileges at runtime.
