{"schemaVersion":3,"id":"CVE-2023-1862","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Cloudflare WARP client for Windows (up to v2023.3.381.0) allowed a malicious actor to remotely access the warp-svc.exe binary due to an insufficient access control policy on an IPC Named Pipe. This would have enabled an attacker to trigger WARP connect and disconnect commands, as well as obtaining network diagnostics and application configuration from the target's device. It is important to note that in order to exploit this, a set of requirements would need to be met, such as the target's device must've been reachable on port 445, allowed authentication with NULL sessions or otherwise having knowledge of the target's credentials.","dates":{"published":"2023-06-20T08:28:12.578Z","modified":"2024-12-09T18:31:09.155Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.3,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.3,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.3,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00754,"percentile":0.54328,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00754},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00754,"percentile":0.54328}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00754,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","scor
