Apache Linkis Spark EngineConn: Inadequate Encryption Strength

Published Updated By the CyberSecBulletin desk

CVE-2024-39928 is a high-severity inadequate encryption strength vulnerability in Apache Linkis Spark EngineConn from Apache, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.6.0 as the first without the flaw, so updating Apache Linkis Spark EngineConn to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Apache Linkis Spark EngineConn to 1.6.0 or a later version.
  2. Update Linkis to 1.6.0 or a later version.
  3. Read the advisory on lists.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.

The underlying weakness: Inadequate Encryption Strength

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

How developers prevent this class of flaw

  • Use an encryption scheme that is currently considered to be strong by experts in the field.
