Broadcom based cable modems across multiple vendors are vulnerable to a buffer overflow, which allows a remote attacker to execute arbitrary code at the kernel level via JavaScript run in a victim's browser. Examples of affected products include Sagemcom F@st 3890 prior to 50.10.21_T4, Sagemcom F@st 3890 prior to 05.76.6.3f, Sagemcom F@st 3686 3.428.0, Sagemcom F@st 3686 4.83.0, NETGEAR CG3700EMR 2.01.05, NETGEAR CG3700EMR 2.01.03, NETGEAR C6250EMR 2.01.05, NETGEAR C6250EMR 2.01.03, Technicolor TC7230 STEB 01.25, COMPAL 7284E 5.510.5.11, and COMPAL 7486E 5.510.5.11.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.8, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 14 products from sagemcom, from sagemcom, from sagemcom and 11 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2020, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For sagemcom's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
