SNMP Access-Control Bypass in Technicolor Devices

CVE-2017-5135

What is CVE-2017-5135?

Technicolor devices, particularly the DPC3928SL model, are vulnerable to an SNMP access-control bypass. This vulnerability allows unauthorized access using any SNMP community string, potentially facilitating unauthorized configurations or data access from external sources. The issue may be exacerbated by specific ISP customizations, which could influence device security settings. Additionally, due to the presence of write properties in the Management Information Base (MIB), attackers can leverage this to execute harmful actions, demonstrating the critical need for effective security measures to protect affected devices.
