CVE intelligence and bounded remediation

CVE-2020-9137 — There is a privilege escalation vulnerability in some versions of CloudEngine 12800,CloudEngine 5800,CloudEngine 6800 and CloudEngine 7800

Medium CVSS 6.7

There is a privilege escalation vulnerability in some versions of CloudEngine 12800,CloudEngine 5800,CloudEngine 6800 and CloudEngine 7800. Due to insufficient input validation, a local attacker with high privilege may execute some specially crafted scripts in the affected products. Successful exploit will cause privilege escalation.

Matched remediation archetype

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
