dataease: Deserialization of Untrusted Data

Published Updated By the CyberSecBulletin desk

CVE-2024-23328 is a critical-severity deserialization of untrusted data vulnerability in dataease, with a CVSS 3.1 base score of 9.1 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 1.18.15, 2.3.0 as the first without the flaw, so updating dataease to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.21% chance of exploitation within 30 days, higher than 69% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update dataease to 1.18.15 or 2.3.0, whichever matches your release line, or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Dataease is an open source data visualization analysis tool. A deserialization vulnerability exists in the DataEase datasource, which can be exploited to execute arbitrary code. The location of the vulnerability code is `core/core-backend/src/main/java/io/dataease/datasource/type/Mysql.java.` The blacklist of mysql jdbc attacks can be bypassed and attackers can further exploit it for deserialized execution or reading arbitrary files. This vulnerability is patched in 1.18.15 and 2.3.0.

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.
