Technical details

This vulnerability is an authorization bypass through user-controlled key (CWE-639) in Dell PowerProtect One versions 20.1.0.0 and earlier. A low-privileged, authenticated remote attacker can exploit a flawed authorization mechanism that relies on user-supplied input to gain unauthorized access to sensitive functions. The attack requires network access and valid low-privilege credentials, but no user interaction. Successful exploitation allows an attacker to modify (tamper with) data and configurations. Dell has released security patches to address this issue.
