One of these features is validating whether or not a supplied URL is valid or not. To do this, uri-js uses a regular expression, This regular expression is vulnerable to redos. This causes the program to hang and the CPU to idle at 100% usage while uri-js is trying to validate if the supplied URL is valid or not. To check if you're vulnerable, look for a call to `require(\"uri-js\").parse()` where a user is able to send their own input. This affects uri-js 2.1.1 and earlier."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-400"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2017-16021", "ASSIGNER": "cve-assignments@hackerone.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 6.8, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:S/C:N/I:N/A:C", "authentication": "SINGLE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "COMPLETE", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "impactScore": 6.9, "obtainAllPrivilege": false, "exploitabilityScore": 8.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.0", "baseScore": 6.5, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 2.8}}, "publishedDate": "2018-06-04T19:29Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:uri-js_project:uri-js:*:*:*:*:*:node.js:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "2.1.1"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2019-10-09T23:24Z"}
