CVE-2023-23120 : What You Need to Know

This CVE involves a vulnerability in the TRENDnet TV-IP651WI Network Camera firmware version v1.07.01 and earlier, where the use of the cyclic redundancy check (CRC) algorithm for integrity check during firmware updates makes it susceptible to firmware modification attacks. Attackers can exploit this vulnerability to conduct man-in-the-middle (MITM) attacks and manipulate the new firmware image to evade checksum verification.

Understanding CVE-2023-23120

In this section, we will delve into the details of CVE-2023-23120, exploring what it entails and its potential impact.

What is CVE-2023-23120?

CVE-2023-23120 highlights a security loophole in the TRENDnet TV-IP651WI Network Camera firmware versions v1.07.01 and earlier due to the flawed implementation of the CRC algorithm for integrity checks during firmware updates.

The Impact of CVE-2023-23120

The vulnerability opens the door for malicious actors to intercept firmware updates, modify them, and circumvent checksum verification processes. This could lead to unauthorized firmware alterations, potentially compromising the security and functionality of the affected devices.

Technical Details of CVE-2023-23120

This section will provide a deeper look into the technical aspects of CVE-2023-23120, including the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description
