Pentaho Data Integration & Analytics: Deserialization of Untrusted Data

Published Updated By the CyberSecBulletin desk

CVE-2024-37361 is a critical-severity deserialization of untrusted data vulnerability in Pentaho Data Integration & Analytics from Hitachi Vantara, with a CVSS 3.1 base score of 9.9 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 10.2.0.0 as the first without the flaw, so updating Pentaho Data Integration & Analytics to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.52% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Official description

The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid. (CWE-502) Hitachi Vantara Pentaho Business Analytics Server versions before 10.2.0.0 and 9.3.0.9, including 8.3.x, deserialize untrusted JSON data without constraining the parser to approved classes and methods. When developers place no restrictions on "gadget chains," or series of instances and method invocations that can self-execute during the deserialization process (i.e., before the object is returned to the caller), it is sometimes possible for attackers to leverage them to perform unauthorized actions.

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.
