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

serialize-javascript prior to 3.1.0 allows remote attackers to inject arbitrary code via the function deleteFunctions within index.js.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Serialize-javascript Verizon * 3.1.0 (excluding)
OpenShift Service Mesh 1.0 RedHat servicemesh-grafana-0:6.2.2-38.el8 *
OpenShift Service Mesh 1.1 RedHat servicemesh-grafana-0:6.4.3-11.el8 *

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.
