OVERVIEW

Remote Code Execution on the server through adaptive authentication script.

DESCRIPTION

For this vulnerability to have any impact on your deployment, the malicious actor should have one of the following permissions to exploit the vulnerability using Adaptive Authentication script:

• /permission/admin/manage/identity/applicationmgt/create
• /permission/admin/manage/identity/applicationmgt/update

If the malicious actor has /permission/admin/manage permission, the vulnerability can be exploited using function libraries. When the above preconditions are met, a malicious actor could gain access to the server by running malicious code.

IMPACT

There is no impact on your deployment if all the preconditions mentioned in the description section are not met. If preconditions are met, by leveraging this vulnerability, a malicious actor may gain Remote Code Execution on the server. By doing so, the server data is at a high-risk, resulting in an impact on confidentiality, integrity and availability of data.
