Dell EMC Networking X-Series firmware versions 3.0.1.2 and older, Dell EMC Networking PC5500 firmware versions 4.1.0.22 and older and Dell EMC PowerEdge VRTX Switch Modules firmware versions 2.0.0.77 and older contain an information disclosure vulnerability. A remote unauthenticated attacker could exploit this vulnerability to retrieve sensitive data by sending a specially crafted request to the affected endpoints.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.
