According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to win a race condition. According to the CVSS score, the attack vector is adjacent (AV:A). What does this mean for this vulnerability? Exploiting this vulnerability requires an attacker to be on the same network segment as the target system. Traffic associated with exploitation of this vulnerability is not routable and is bound to the data link layer of the OSI model. According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do? A user would need to dial a PPPoE connection at the same time an attacker was attempting to exploit the vulnerability.
