## Key facts

- **Exploitation phase:** Limited Exploitation. The vulnerability is known but shows very limited attacker interest or exploitation activity.
- **CVSS score:** 8.0
- **Public exploit available:** Yes
- **Affected products:** ZoneMinder
- **Weaknesses:** CWE-287 (Improper Authentication)
- **Tags:** web_application

## Description

ZoneMinder is a free, open source Closed-circuit television software application. In affected versions authenticated users can bypass CSRF keys by modifying the request supplied to the Zoneminder web application. These modifications include replacing HTTP POST with an HTTP GET and removing the CSRF key from the request. An attacker can take advantage of this by using an HTTP GET request to perform actions with no CSRF protection. This could allow an attacker to cause an authenticated user to perform unexpected actions on the web application. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.
