CVE-2023-3324

A vulnerability exists by allowing low-privileged users to read and update the data in various directories used by the Zenon system. An attacker could exploit the vulnerability by using specially crafted programs to exploit the vulnerabilities by allowing them to run on the zenon installed hosts. This issue affects ABB Ability™ zenon: from 11 build through 11 build 106404.

Weakness

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

Affected Software

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.
