Microsoft SQL Server Remote Code Execution Vulnerability

Weakness

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

Affected Software

Name Vendor Start Version End Version
Sql_server Microsoft 2012-sp4 (including) 2012-sp4 (including)
Sql_server Microsoft 2014-sp3 (including) 2014-sp3 (including)
Sql_server Microsoft 2016-sp3 (including) 2016-sp3 (including)
Sql_server Microsoft 2017 (including) 2017 (including)
Sql_server Microsoft 2019 (including) 2019 (including)
Sql_server Microsoft 2022 (including) 2022 (including)

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.
