An unauthenticated attacker can exploit this vulnerability by manipulating URL to achieve arbitrary file read access.This issue affects Valmet DNA Web Tools: C2022 and older.

Local privilege escalation through insecure DCOM configuration in Valmet DNA versions prior to C2023. The DCOM object Valmet DNA Engineering has permissions that allow it to run commands as a user with the SeImpersonatePrivilege privilege. The SeImpersonatePrivilege privilege is a Windows permission that allows a process to impersonate another user. An attacker can use this vulnerability to escalate their privileges and take complete control of the system.

Lack of protection against brute force attacks in Valmet DNA visualization in DNA Operate. The possibility to make an arbitrary number of login attempts without any rate limit gives an attacker an increased chance of guessing passwords and then performing switching operations.

Valmet DNA user passwords in plain text. This practice poses a security risk as attackers who gain access to local project data can read the passwords.
