An attacker could exploit this vulnerability by sending a valid low-privileged SSH key to an affected device from a host that has an IP address that is configured as the source for a high-privileged user account. A successful exploit could allow the attacker to log in to the affected device through SSH as a high-privileged user.\r\n\r There are workarounds that address this vulnerability." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 2.8, "impactScore": 5.9 }, { "source": "ykramarz@cisco.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 2.8, "impactScore": 5.9 } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-522" } ] } ], "configurations": [ { "operator": "AND", "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionEndExcluding": "21.22.14", "matchCriteriaId": "1280E939-FA8A-49E4-AE06-616B152929CF" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionStartIncluding": "21.23.0", "versionEndExcluding": "21.23.31", "matchCriteriaId": "5A2C7A63-E17A-487D-8CCF-3346FDA2859F" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionStartIncluding": "21.25.0", "versionEndExcluding": "21.25.15", "matchCriteriaId": "1B58A574-77D9-4EC5-9D57-8D244EF7BDB8" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionStartIncluding": "21.26.0", "versionEndExcluding": "21.26.17", "matchCriteriaId": "E9507CCB-0340-40D6-AAF3-D2EA3D3EE408" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionStartIncluding": "21.27.0", "versionEndExcluding": "21.27.6", "matchCriteriaId": "0D9F9D50-DA13-410A-9571-6FA9436165E8" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*", "versionStartIncluding": "21.28.0", "versionEndExcluding": "21.28.3", "matchCriteriaId": "833F9A52-2976-4F2C-AA87-FD50BB83BB3D" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:21.23.n:*:*:*:*:*:*:*", "matchCriteriaId": "CD63EE8D-0389-4589-BF86-0F64A8AEDA13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:21.24:*:*:*:*:*:*:*", "matchCriteriaId": "A0534E44-1CD6-49CB-A574-D7B2CF14CC25" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:21.27.m:*:*:*:*:*:*:*", "matchCriteriaId": "CC1BBD53-BF16-4841-9D20-D2C4129A337B" }, { "vulnerable": true, "criteria": "cpe:2.3:o:cisco:staros:21.28.m:*:*:*:*:*:*:*", "matchCriteriaId": "47DCE4FD-48D4-4B25-BBAE-24D270627FCD" } ] }, { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": false, "criteria": "cpe:2.3:h:cisco:asr_5000:-:*:*:*:*:*:*:*", "matchCriteriaId": "746254AC-B039-432C-AA5C-A82260E57AD7" }, { "vulnerable": false, "criteria": "cpe:2.3:h:cisco:asr_5500:-:*:*:*:*:*:*:*", "matchCriteriaId": "301681DF-2A9E-4A91-9918-4A46153ADC01" }, { "vulnerable": false, "criteria": "cpe:2.3:h:cisco:asr_5700:-:*:*:*:*:*:*:*", "matchCriteriaId": "A9EF0299-16A7-446D-855D-BFF91EE65534" }, { "vulnerable": false, "criteria": "cpe:2.3:h:cisco:vpc-di:-:*:*:*:*:*:*:*", "matchCriteriaId": "775B2FC4-E182-47F8-B786-EC6A359BCCE3" }, { "vulnerable": false, "criteria": "cpe:2.3:h:cisco:vpc-si:-:*:*:*:*:*:*:*", "matchCriteriaId": "DFD5A5BE-9B00-4E4F-A4A4-FBEF990F4C39" } ] } ] } ], "references": [ { "url": "https://github.com/orangecertcc/security-research/security/advisories/GHSA-j7p3-gjw6-pp4r", "source": "ykramarz@cisco.com", "tags": [ "Third Party Advisory" ] }, { "url": "https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-staros-ssh-privesc-BmWeJC3h", "source": "ykramarz@cisco.com", "tags": [ "Vendor Advisory" ] } ] }
