7.8
CVSS v3.1
Official Description
THOMSON THT741FTA 2.2.1 and Philips DTR3502BFTA DVB-T2 2.2.1 set-top boxes have their TELNET service hardcoded to start on boot, which allows an attacker on the local network to achieve root access via the TELNET protocol.
Technical Analysis
CVE-2020-11618 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
