What is CVE-2021-41553?
CVE-2021-41553 is a critical authentication bypass vulnerability in n/a, published on 5 Oct 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
In ARCHIBUS Web Central 21.3.3.815 (a version from 2014), the Web Application in /archibus/login.axvw assign a session token that could be already in use by another user. It was therefore possible to access the application through a user whose credentials were not known, without any attempt by the testers to modify the application logic. It is also possible to set the value of the session token, client-side, simply by making an unauthenticated GET Request to the Home Page and adding an arbitrary value to the JSESSIONID field. The application, following the login, does not assign a new token, continuing to keep the inserted one, as the identifier of the entire session. This is fixed in all recent versions, such as version 26. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Version 21.3 was officially de-supported by the end of 2020
