Exploitability The following table provides an exploitability assessment for this vulnerability at the time of original publication. Publicly disclosed No Exploited No Exploitability assessment Exploitation Less Likely FAQ How could an attacker exploit this vulnerability? To exploit this vulnerability, an unauthenticated attacker would need to send malformed packets to a websocket listening port. This could result in remote code execution on the server side with the same permissions as the websocket service. 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.
