An attacker can craft a URL such as /api/v2/ilove.svg?love=<script>...</script>; when a victim navigates to it the injected script executes in the victim browser in the origin of the Netdata instance (reflected cross-site scripting). These endpoints are registered with HTTP_ACL_NOCHECK and anonymous access and, because bearer-token protection is disabled by default, are reachable without authentication on a default Netdata agent. The issue was resolved by removing the ilove endpoint."}], "tags": ["x_open-source"], "datePublic": "2025-03-20T00:00:00.000Z", "problemTypes": [{"descriptions": [{"lang": "en", "cweId": "CWE-79", "description": "Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", "type": "CWE"}]}], "affected": [{"vendor": "netdata", "product": "netdata", "defaultStatus": "unaffected", "versions": [{"version": "0", "status": "affected", "lessThan": "2.3.1", "versionType": "semver"}], "repo": "https://github.com/netdata/netdata"}], "cpeApplicability": [{"nodes": [{"operator": "OR", "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:netdata:netdata:*:*:*:*:*:*:*:*", "versionEndExcluding": "2.3.1"}]}]}], "metrics": [{"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV3_1": {"attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE", "version": "3.1", "baseSeverity": "MEDIUM", "baseScore": 6.1, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}}, {"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV4_0": {"attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "ACTIVE", "vulnConfidentialityImpact": "NONE", "subConfidentialityImpact": "LOW", "vulnIntegrityImpact": "NONE", "subIntegrityImpact": "LOW", "vulnAvailabilityImpact": "NONE", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "MEDIUM", "baseScore": 5.1, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}}], "references": [{"url": "https://github.com/netdata/netdata/releases/tag/v2.3.1", "name": "Release Notes", "tags": ["release-notes"]}, {"url": "https://github.com/netdata/netdata/pull/19919", "name": "Fix PR", "tags": ["issue-tracking"]}, {"url": "https://github.com/netdata/netdata/commit/f82554fe9b21b5ae51a8663a3f4ddce84cac16af", "name": "Fix Commit", "tags": ["patch"]}, {"url": "https://www.vulncheck.com/advisories/netdata-reflected-cross-site-scripting-via-love-parameter-in-ilove-svg-endpoint", "tags": ["third-party-advisory"]}], "credits": [{"lang": "en", "value": "George Chen", "type": "finder"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
