Detection & IOCsextracted from sources · hover to see the quote

  • Block polymorphic deserialization of blaze-ds-opt and blaze-ds-core classes in jackson-databind to prevent arbitrary code execution
  • Exploitation requires the blaze-ds gadget jars to be present on the classpath; absence of blaze-ds libraries renders the vulnerability unexploitable regardless of jackson-databind version
  • Review upstream patch commit 87d29af25e82a249ea15858e2d4ecbf64091db44 for the exact class-blocklist additions to use in detection/prevention logic
  • ·Vulnerability only affects jackson-databind 2.x versions before 2.9.7; upgrade to 2.9.7 or later (e.g., 2.9.8) to remediate
  • ·Exploitation requires polymorphic deserialization (e.g., default typing) to be enabled in the application's jackson-databind configuration; applications not using this feature are not directly exploitable
