Deserialization of Untrusted Data vulnerability in OpenText™ Directory Services allows Object Injection.
The vulnerability could lead to remote code execution, denial of service, or privilege escalation.
This issue affects Directory Services: before 24.4.16, from 25.1 before 25.1.9, from 25.2 before 25.2.9, from 25.3 before 25.3.8, from 25.4 before 25.4.5, from 26.1 before 26.1.2.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
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.
