Linksys WRT310N wireless router firmware contains a vulnerability that could allow an authenticated, remote attacker to cause a denial of service condition. Updates are not available.
Multiple vulnerabilities in Linksys WRT310N wireless routers running firmware version 2 could allow an authenticated, remote attacker to cause a denial of service (DoS) condition.
The vulnerabilities are due to a condition in the apply.cgi page, which allows HTML forms to be submitted via both HTTP POST and HTTP GET requests. An authenticated, remote attacker could exploit these vulnerabilities by sending crafted HTTP requests to a targeted system. A successful exploit could cause the system to crash, resulting in a DoS condition.
Proof-of-concept code is publicly available.
Linksys has not confirmed these vulnerabilities and software updates are not available.
Administrators are advised to contact the vendor regarding future updates and releases.
Administrators are advised to allow only privileged users to access administration or management systems.
