The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2021-11-11T22:37:55.000000Z"}, {"uuid": "b11b1c1a-1ce2-4188-a3fb-3e3bf6a7b8e1", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2002-20001", "type": "published-proof-of-concept", "source": "https://t.me/CyberSecurityTechnologies/5006", "content": "#tools\nD(HE)ater is a PoC implementation of the D(HE)at attack (CVE-2002-20001) through which DoS can be performed by enforcing the DHE key exchange\nhttps://github.com/Balasys/dheater", "creation_timestamp": "2021-12-19T13:30:32.000000Z"}, {"uuid": "8d388205-c90a-4d6c-b287-c576fe85e026", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2002-20001", "type": "seen", "source": "https://t.me/GithubRedTeam/88658", "content": "\ud83d\udea8 GitHub \u76d1\u63a7\u6d88\u606f\u63d0\u9192\n\n\ud83d\udea8 \u53d1\u73b0\u5173\u952e\u8bcd\uff1a #GitLab #CVE #POC\n\n\ud83d\udce6 \u9879\u76ee\u540d\u79f0\uff1a dheater\n\ud83d\udc64 \u9879\u76ee\u4f5c\u8005\uff1a c0r0n3r\n\ud83d\udee0 \u5f00\u53d1\u8bed\u8a00\uff1a Python\n\u2b50 Star\u6570\u91cf\uff1a 216  |  \ud83c\udf74 Fork\u6570\u91cf\uff1a 30\n\ud83d\udcc5 \u66f4\u65b0\u65f6\u95f4\uff1a 2026-06-13 15:02:58\n\n\ud83d\udcdd \u9879\u76ee\u63cf\u8ff0\uff1a\nD(HE)ater is a proof of concept implementation of the D(HE)at  attack (CVE-2002-20001) through which denial-of-service can be performed by enforcing the Diffie-Hellman key exchange.
