NVD-CWE-OtherPublished: May 31, 2005· Updated: Jun 16, 2026
Official Description
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.
Technical Analysis
CVE-2005-0356 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2005-0356. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
