Brocade SANnav: Exposure of Sensitive Information to an Unauthorized Actor

Published Updated By the CyberSecBulletin desk

CVE-2024-29961 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in Brocade SANnav from Brocade, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Brocade SANnav versions: before v2.3.1 and v2.3.0a. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.76% chance of exploitation within 30 days, higher than 56% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update sannav to 2.3.1 or 2.3.0a, whichever matches your release line, or a later version.
  2. Read the advisory on support.broadcom.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A vulnerability affects Brocade SANnav before v2.3.1 and v2.3.0a. It allows a Brocade SANnav service to send ping commands in the background at regular intervals to gridgain.com to check if updates are available for the Component. This could make an unauthenticated, remote attacker aware of the behavior and launch a supply-chain attack against a Brocade SANnav appliance.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How developers prevent this class of flaw

  • 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.
