Apache Camel: Deserialization of Untrusted Data

Published Updated By the CyberSecBulletin desk

CVE-2024-23114 is a critical-severity deserialization of untrusted data vulnerability in Apache Camel from Apache, with a CVSS 3.1 base score of 9.8 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 3.21.4, 3.22.1, 4.0.4 as the first without the flaw, so updating Apache Camel to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.27% chance of exploitation within 30 days, higher than 70% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Apache Camel to 3.21.4 or 3.22.1 or 4.0.4 or 4.4.0, whichever matches your release line, or a later version.
  2. Update camel to 3.21.4 or 3.22.1 or 4.0.4 or 4.4.0, whichever matches your release line, or a later version.
  3. Read the advisory on camel.apache.org for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Deserialization of Untrusted Data vulnerability in Apache Camel CassandraQL Component AggregationRepository which is vulnerable to unsafe deserialization. Under specific conditions it is possible to deserialize malicious payload.This issue affects Apache Camel: from 3.0.0 before 3.21.4, from 3.22.0 before 3.22.1, from 4.0.0 before 4.0.4, from 4.1.0 before 4.4.0. Users are recommended to upgrade to version 4.4.0, which fixes the issue. If users are on the 4.0.x LTS releases stream, then they are suggested to upgrade to 4.0.4. If users are on 3.x, they are suggested to move to 3.21.4 or 3.22.1

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.
