CWEhttps://cwe.mitre.org/data/definitions/502.html

The IBM SDK, Java Technology Editions Object Request Broker (ORB) 7.1.0.0 through 7.1.5.21 and 8.0.0.0 through 8.0.8.21 is vulnerable to a denial of service attack in some circumstances due to improper enforcement of the JEP 290 MaxRef and MaxDepth deserialization filters. IBM X-Force ID: 260578.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Java_software_development_kit Ibm 7.1.0.0 (including) 7.1.5.22 (excluding)
Java_software_development_kit Ibm 8.0.0.0 (including) 8.0.8.25 (excluding)
Red Hat Enterprise Linux 7 Supplementary RedHat java-1.8.0-ibm-1:1.8.0.8.25-1jpp.1.el7 *
Red Hat Enterprise Linux 8 RedHat java-1.8.0-ibm-1:1.8.0.8.25-1.el8_10 *

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
