EPMM: Deserialization of Untrusted Data

CVE-2024-36131 is a high-severity deserialization of untrusted data vulnerability in EPMM from Ivanti, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 12.1.0.1 as the first without the flaw, so updating EPMM to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.29% chance of exploitation within 30 days, higher than 84% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update EPMM to 12.1.0.1 or a later version.
  2. Update endpoint_manager_mobile to 12.1.0.1 or a later version.
  3. Read the advisory on forums.ivanti.com for workarounds and exact fixed builds.

Official description

An insecure deserialization vulnerability in web component of EPMM prior to 12.1.0.1 allows an authenticated remote attacker to execute arbitrary commands on the underlying operating system of the appliance.

The underlying weakness: Deserialization of Untrusted Data

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

How developers prevent this class of flaw

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
  • Explicitly define a final object() to prevent deserialization.
