February 28, 2024: Progress OpenEdge authentication bypass vulnerability CVE-2024-1403


Censys is aware that on February 27, 2024, a critical vulnerability was published for OpenEdge’s Authentication Gateway and AdminServer across all platforms prior to 11.7.19, 12.2.14, 12.8.1. It allows for authentication bypass, via mishandled username/password, to Authentication Gateway and AdminServer assets that can result in unauthorized, unauthenticated access.


Since the OpenEdge Authentication Gateway is an identity management tool, an unauthorized authentication bypass could allow an attacker unauthorized access to the stored user information including user names and passwords (Securityonline). Additionally, this could permit an attacker the ability to manipulate accounts in order to obtain access to the enterprise assets for which OpenEdge manages access.

Affected Assets

According to the NVD, this issue affects all OpenEdge Authentication Gateway and AdminServer platforms prior to 11.7.19, 12.2.14, 12.8.1 including:
OpenEdge LTS 11.7.18
OpenEdge LTS 12.2.13
OpenEdge LTS 12.8.0

Censys’ Rapid Response Team was able to identify all publicly exposed OpenEdge application servers, OpenEdge Explorer (OEE) web interfaces, and OpenEdge Management (OEM) web interfaces. Note that Censys was unable to obtain version information due to the lack of response information from these assets.
