-
Attack Vector: Network
-
Privileges Required: NoneFeedly+2NVD+2CVE+2
-
User Interaction: Required
-
Impact: Potential execution of malicious scripts in the user’s browser
Affected Products
The vulnerability affects the Genie Aladdin Connect garage door opener, specifically the Retrofit-Kit Model ALDCM.GitHub+4NVD+4CVE+4
How the Exploit Works
When the Genie Aladdin Connect device enters configuration mode, it hosts a web server for setup purposes. An attacker can exploit this by broadcasting a Wi-Fi SSID containing malicious JavaScript or HTML code. If a user connects to the device and accesses the setup page, the malicious code embedded in the SSID can execute in the user’s browser, leading to potential security breaches.NVD+4Recorded Future+4Feedly+4GitHub+4Feedly+4Recorded Future+4
