Name of the Vulnerable Software and Affected Versions BrightSign Digital Signage Diagnostic Web Server versions 8.2.26 and earlier
Description The software contains an unauthenticated server-side request forgery issue. This affects the 'url' GET parameter within the Download Speed Test service. An attacker can specify external domains, potentially bypassing firewalls and performing network enumeration. This is achieved by forcing the application to make arbitrary HTTP requests to internal network hosts. The vulnerable parameter is url.
Recommendations Versions prior to 8.2.26 should be updated.
