Official Description
The Uboot bootloader on the Verizon Wireless Network Extender SCS-2U01 allows physically proximate attackers to bypass the intended boot process and obtain a login prompt by connecting a crafted HDMI cable and sending a SysReq interrupt.
Technical Analysis
CVE-2013-4875 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
