Industrial Edge Management Pro: Authorization Bypass Through User-Controlled Key

Published Updated By the CyberSecBulletin desk

CVE-2024-45032 is a critical-severity authorization bypass through user-controlled key vulnerability in Industrial Edge Management Pro from Siemens, with a CVSS 3.1 base score of 10.0 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 V1.9.5, 1.9.5 as the first without the flaw, so updating Industrial Edge Management Pro to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.76% chance of exploitation within 30 days, higher than 56% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Industrial Edge Management Pro to V1.9.5 or 1.9.5, whichever matches your release line, or a later version.
  2. Update Industrial Edge Management Virtual to V2.3.1-1 or 2.3.1-1, whichever matches your release line, or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A vulnerability has been identified in Industrial Edge Management Pro (All versions < V1.9.5), Industrial Edge Management Virtual (All versions < V2.3.1-1). Affected components do not properly validate the device tokens. This could allow an unauthenticated remote attacker to impersonate other devices onboarded to the system.

The underlying weakness: Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How developers prevent this class of flaw

  • For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
