Title: A-Link WL54AP3 and WL54AP2 Cross Site Request Forgery and HTML Injection Vulnerabilities
Severity: MODERATE
Description:
A-Link WL54AP3 and WL54AP2 are wireless routers.
The routers are prone to multiple remote vulnerabilities:
1. A cross-site request-forgery vulnerability may allow attackers to change DNS servers, enable the WAN webserver, and change usernames and passwords.
2. An HTML-injection vulnerability affects the 'Domain name' textbox' included in the management interface.
To successfully exploit these issues, the attacker must know the management interface IP address for the affected device.
The attacker can exploit the cross-site request forgery issue to alter administrative configuration on affected devices. This may lead to further network-based attacks.
The attacker can exploit the HTML-injection issue to execute arbitrary script code in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
