In addition, Harbor system administrators can enforce a setting where only an administrator is allowed to create new projects instead of the default Everyone. This further restricts who can be a project administrator in Harbor.\n\n# For more information\nIf you have any questions or comments about this advisory, contact cncf-harbor-security@lists.cncf.io\nView our security policy at https://github.com/goharbor/harbor/security/policy\nhttps://nvd.nist.gov/vuln/detail/CVE-2020-13788\nhttps://www.soluble.ai/blog/harbor-ssrf-cve-2020-13788", "published": "2022-02-11T23:17:02", "modified": "2023-01-09T05:04:57", "epss": [{"cve": "CVE-2020-13788", "epss": 0.00081, "percentile": 0.33809, "modified": "2023-12-03"}], "cvss": {"score": 4.0, "vector": "AV:N/AC:L/Au:S/C:P/I:N/A:N"}, "cvss2": {"cvssV2": {"version": "2.0", "vectorString": "AV:N/AC:L/Au:S/C:P/I:N/A:N", "accessVector": "NETWORK", "accessComplexity": "LOW", "authentication": "SINGLE", "confidentialityImpact": "PARTIAL", "integrityImpact": "NONE", "availabilityImpact": "NONE", "baseScore": 4.0}, "severity": "MEDIUM", "exploitabilityScore": 8.0, "impactScore": 2.9, "acInsufInfo": false, "obtainAllPrivilege": false, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "cvss3": {"cvssV3": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "availabilityImpact": "NONE", "baseScore": 4.3, "baseSeverity": "MEDIUM"}, "exploitabilityScore": 2.8, "impactScore": 1.4}, "href": "https://github.com/advisories/GHSA-33p6-fx42-7rf5", "reporter": "GitHub Advisory Database", "references": ["https://github.com/goharbor/harbor/security/advisories/GHSA-33p6-fx42-7rf5", "https://nvd.nist.gov/vuln/detail/CVE-2020-13788", "https://github.com/goharbor/harbor/releases", "https://www.soluble.ai/blog/harbor-ssrf-cve-2020-13788", "https://www.youtube.com/watch?v=v8Isqy4yR3Q", "https://github.com/advisories/GHSA-33p6-fx42-7rf5"], "cvelist": ["CVE-2020-13788"], "immutableFields": [], "lastseen": "2023-12-03T17:28:20", "viewCount": 8, "enchantments": {"backreferences": {"references": [{"type": "cve", "idList": ["CVE-2020-13788"]}, {"type": "kitploit", "idList": ["KITPLOIT:116690769744039319"]}]}, "dependencies": {"references": [{"type": "cve", "idList": ["CVE-2020-13788"]}, {"type": "osv", "idList": ["OSV:GHSA-33P6-FX42-7RF5"]}, {"type": "prion", "idList": ["PRION:CVE-2020-13788"]}, {"type": "veracode", "idList": ["VERACODE:25894"]}]}, "exploitation": null, "score": {"value": 0.9, "vector": "NONE"}, "affected_software": {"major_version": [{"name": "github.com/goharbor/harbor", "version": 1}, {"name": "github.com/goharbor/harbor", "version": 2}]}, "epss": [{"cve": "CVE-2020-13788", "epss": 0.00081, "percentile": 0.33208, "modified": "2023-05-01"}], "vulnersScore": 0.9}, "_state": {"dependencies": 1701624784, "score": 1701624911, "affected_software_major_version": 0, "epss": 0}, "_internal": {"score_hash": "a6ba48fda1906193ee69300d9666543d"}, "affectedSoftware": [{"version": "1.8.0", "operator": "ge", "ecosystem": "GO", "name": "github.com/goharbor/harbor"}, {"version": "2.0.1", "operator": "lt", "ecosystem": "GO", "name": "github.com/goharbor/harbor"}]}
