The vulnerability arises out of a failure to comprehensively sanitize the processing of .tar file (tape archives). The vulnerability stems from incomplete input validation of a user-supplied .tar file as it pertains to the names of the files contained within the archive. As a consequence, a remote attacker can specifically format these file names in a particular manner that will result in remotely executing a system command through Perl's qx operator with the privileges of the Email Security Gateway product. This issue was fixed as part of BNSF-36456 patch. This patch was automatically applied to all customer appliances."}],"metrics":{"cvssMetricV31":[{"source":"cve-coordination@google.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","baseScore":9.4,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":5.5},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":5.9}]},"cisaExploitAdd":"2023-05-26","cisaActionDue":"2023-06-16","cisaRequiredAction":"Apply updates per vendor instructions.","cisaVulnerabilityName":"Barracuda Networks ESG Appliance Improper Input Validation Vulnerability","weaknesses":[{"source":"cve-coordination@google.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-77"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:barracuda:email_security_gateway_300_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1.3.001","versionEndIncluding":"9.2.0.006","matchCriteriaId":"F270DBDA-EE31-4AF0-8743-D742467485CF"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:barracuda:email_security_gateway_300:-:*:*:*:*:*:*:*","matchCriteriaId":"824DAE15-3628-4346-947E-C33FA46AADE6"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:barracuda:email_security_gateway_400_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1.3.001","versionEndIncluding":"9.2.0.006","matchCriteriaId":"4A9B9E0B-F8D4-4626-AD39-BD525D638693"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:barracuda:email_security_gateway_400:-:*:*:*:*:*:*:*","matchCriteriaId":"ACD3DD62-D690-47F9-8416-61AD78B33699"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:barracuda:email_security_gateway_600_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1.3.001","versionEndIncluding":"9.2.0.006","matchCriteriaId":"83D228EA-35C8-4B6E-9D22-CF0F7C20362B"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:barracuda:email_security_gateway_600:-:*:*:*:*:*:*:*","matchCriteriaId":"6C507D86-2E68-44A4-A31C-EEF9A6BBEE54"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:barracuda:email_security_gateway_800_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1.3.001","versionEndIncluding":"9.2.0.006","matchCriteriaId":"8ADAC6B0-DE92-41F6-B8B1-1C830BB70C24"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:barracuda:email_security_gateway_800:-:*:*:*:*:*:*:*","matchCriteriaId":"74D999D5-6CE5-49F7-A0C5-0B44704FEE45"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:barracuda:email_security_gateway_900_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"5.1.3.001","versionEndIncluding":"9.2.0.006","matchCriteriaId":"C5A27A43-E632-4C8A-A9F8-49C6E091E7ED"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:barracuda:email_security_gateway_900:-:*:*:*:*:*:*:*","matchCriteriaId":"FFA6EA4B-B0FF-437B-A48E-F11D0CD5EB2B"}]}]}],"references":[{"url":"https://status.barracuda.com/incidents/34kx82j5n4q9","source":"cve-coordination@google.com","tags":["Vendor Advisory"]},{"url":"https://www.barracuda.com/company/legal/esg-vulnerability","source":"cve-coordination@google.com","tags":["Mitigation","Vendor Advisory"]},{"url":"https://status.barracuda.com/incidents/34kx82j5n4q9","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://www.barracuda.com/company/legal/esg-vulnerability","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mitigation","Vendor Advisory"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2023-2868","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["US Government Resource"]}]}}]}
