## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 9.8
- **Public exploit available:** Yes
- **Affected products:** Signup Software Dynamicweb
- **Weaknesses:** CWE-288 (Authentication Bypass Using an Alternate Path or Channel); CWE-287 (Improper Authentication)
- **Tags:** cms, web_application

## Description

An issue was discovered in Dynamicweb before 9.12.8. An attacker can add a new administrator user without authentication. This flaw exists due to a logic issue when determining if the setup phases of the product can be run again. Once an attacker is authenticated as the new admin user they have added, it is possible to upload an executable file and achieve command execution. This is fixed in 9.5.9, 9.6.16, 9.7.8, 9.8.11, 9.9.8, 9.10.18, 9.12.8, and 9.13.0 (and later).

## CrowdSec analysis

[CVE-2022-25369](https://euvd.enisa.europa.eu/vulnerability/CVE-2022-25369) is a critical authentication bypass vulnerability in Dynamicweb versions prior to 9.12.8, where attackers can create new administrator accounts without authentication due to a logic flaw in the setup phase validation. Once an attacker gains admin access, they can upload executable files and achieve remote command execution, leading to full system compromise. This vulnerability poses a severe risk, allowing for complete takeover of affected systems.

CrowdSec has been tracking this vulnerability and its exploits since 15th of April 2026.

Insights from the CrowdSec network reveal that the attackers trying to exploit CVE-2022-25369 are composed of a fairly even mix of opportunistic and targeted actors. Some attackers employ preliminary reconnaissance, while others use indiscriminate scanning.
CrowdSec network telemetry also shows that exploitation of CVE-2022-25369 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit the `/Admin/Access/Setup/Default.aspx` endpoint with the `Action=createadministrator` parameter to create new administrative users without authentication. This allows them to gain full control over vulnerable Dynamicweb CMS installations.
