The manipulation with an unknown input leads to a privilege escalation vulnerability. Using CWE to declare the problem leads to CWE-863. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A security restriction bypass vulnerability has been discovered in Revive Adserver version < 5.0.5 by HackerOne user hoangn144. Revive Adserver, like many other applications, requires the logged in user to type the current password in order to change the e-mail address or the password. It was however possible for anyone with access to a Revive Adserver admin user interface to bypass such check and change e-email address or password of the currently logged in user by altering the form payload.The attack requires physical access to the user interface of a logged in user. If the POST payload was altered by turning the &acirc;&euro;&oelig;pwold&acirc;&euro;&#65533; parameter into an array, Revive Adserver would fetch and authorise the operation even if no password was provided.

The weakness was disclosed 04/03/2020. This vulnerability is handled as CVE-2020-8142 since 01/28/2020. Local access is required to approach this attack. The successful exploitation needs a simple authentication. The technical details are unknown and an exploit is not available.

Upgrading to version 5.0.5 eliminates this vulnerability.
