cdm: Improper Access Control

Published Updated By the CyberSecBulletin desk

CVE-2024-36068 is a critical-severity improper access control vulnerability in cdm from Rubrik, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 9.1.2-p1, 9.0.3-p6, 8.1.3-p12 as the first without the flaw, so updating cdm to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.49% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update cdm to 9.1.2-p1 or 9.0.3-p6 or 8.1.3-p12, whichever matches your release line, or a later version.
  2. Update Cloud Data Management to 8.1.3 or 9.0.3 or 9.1.2, whichever matches your release line, or a later version.
  3. Read the advisory on rubrik.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

An incorrect access control vulnerability in Rubrik CDM versions prior to 9.1.2-p1, 9.0.3-p6 and 8.1.3-p12, allows an attacker with network access to execute arbitrary code.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
