Improper certificate validation in Visual Studio allows an unauthorized attacker to perform spoofing over a network.
According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? The attacker must inject themselves into the logical network path between the target and the resource requested by the victim to read or modify network communications. This is called a machine-in-the-middle (MITM) attack. According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H), and integrity (I:H), but could lead to no loss of availability (A:N). What does that mean for this vulnerability? Exploiting this vulnerability allows an attacker to view highly sensitive resource information (C:H) and results in a total loss of protection for that data (I:H), but does not provide the capability to impact resource availability.
