Overview
Multiple vulnerabilities exist in various Video Over IP (Internet Protocol) encoder devices, also known as IPTV/H.264/H.265 video encoders. These vulnerabilities allow an unauthenticated remote attacker to execute arbitrary code and perform other unauthorized actions on a vulnerable system.
Description
IPTV/H.264/H.265 video encoder devices provide video streaming capability over IP networks. The underlying software in these devices seem to share common components that have multiple weaknesses in their design and default configuration.
The vulnerabilities occur primarily in the network services such as web and telnet interfaces. These vulnerabilities stem from software bugs, such as insufficient validation of user input and the use of insecure credentials through hard-coded passwords. https://owasp.org/www-project-top-ten/. The vulnerable components may also be present in other Internet of Things (IoT) devices.
These devices are manufactured using components acquired from a complex supply chain and are often sold through common outlets such as retail stores and e-commerce websites. This makes it difficult to identify impacted devices and notify the appropriate stakeholders, thus illustrating the dire need for Software Bill of Materials SBOM in this growing and complex digital market.
Further details of these vulnerabilities can be found in this blog post by Alexei Kojenov.
Impact
The impact of these vulnerabilities are summarized in the following list:
Full administrative access via backdoor password (CVE-2020-24215)
Administrative root access via backdoor password (CVE-2020-24218)
Arbitrary file read via path traversal (CVE-2020-24219)
