Positive Technologies (AI Summary)

CVSS v3.1

7.5

High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: scapy version 2.4.0

Description: The issue is a Denial of Service that results in an infinite loop, resource consumption, and the program becoming unresponsive. The component affected is the RADIUSAttrPacketListField.getfield(self..) function. The attack vector can be over the network or via a pcap file, with both methods being effective.

Recommendations: For scapy version 2.4.0, consider disabling the RADIUSAttrPacketListField.getfield(self..) function as a temporary workaround to prevent potential exploitation until a patch is available. Restrict access to the network and limit the use of pcap files to minimize the risk of exploitation.
