CVE-2020-8142 | Date: (C)2020-04-08 (M)2023-12-22 |
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 ���pwold��� parameter into an array, Revive Adserver would fetch and authorise the operation even if no password was provided.
