EPMM: Exposure of Sensitive Information to an Unauthorized Actor

Published Updated By the CyberSecBulletin desk

CVE-2023-39337 is a critical-severity exposure of sensitive information to an unauthorized actor vulnerability in EPMM from Ivanti, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected EPMM versions: 11.10.0.0 and earlier; 11.9.0.0 and earlier; 11.8.0.0 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 2.88% chance of exploitation within 30 days, higher than 87% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Endpoint Manager Mobile to 11.10.0.4 or 11.11.0.2, whichever matches your release line, or a later version.
  2. Read the advisory on forums.ivanti.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 security vulnerability in EPMM Versions 11.10, 11.9 and 11.8 older allows a threat actor with knowledge of an enrolled device identifier to access and extract sensitive information, including device and environment configuration details, as well as secrets. This vulnerability poses a serious security risk, potentially exposing confidential data and system integrity.

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.
