TITLE

Telecom Italia Alice Router IP Packet Unauthorized Access Vulnerability

DESCRIPTION

Telecom Italia is Italy's most important ISP, offering ADSL services called Alice. If the intranet user sends the following IP packet to the Alice router: 1) IP protocol number 2552) 8 bytes load size 3) The load is the first 8 bytes of the MD5 data after the br0 device MAC address is deformed 4) These modems The br0 has the same eth0 mac to activate the router's management interface and telnet/ftp/tftp service for unauthorized access. Multiple Telecom Italia routers are prone to an authentication bypass vulnerability that may allow attackers to gain access to a router's administration interface and unauthorized access to certain services. Successfully exploiting this issue will allow attackers to gain unauthorized administrative access to the affected device and activate services such as telnet, ftp, and tftp. The following routers are affected. AGA (Alice Gate2 plus Wi-Fi]) AGB (Alice Gate2 plus) AG2P-AG3 (AG2P-AG3[Alice Gate W2+) AGPV-AGPF (Alice Gate VoIP 2 Plus Wi-Fi). ---------------------------------------------------------------------- Do you need accurate and reliable IDS / IPS / AV detection rules?
