The vulnerability arises out of a failure to comprehensively sanitize the processing of .tar file (tape archives).\u00a0The 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.\u00a0This issue was fixed as part of BNSF-36456 patch. This patch was automatically applied to all customer appliances."}], "lastModified": "2023-06-01T20:14:55.053", "cisaActionDue": "2023-06-16", "cisaExploitAdd": "2023-05-26", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:barracuda:email_security_gateway_300_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F270DBDA-EE31-4AF0-8743-D742467485CF", "versionEndIncluding": "9.2.0.006", "versionStartIncluding": "5.1.3.001"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:barracuda:email_security_gateway_300:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "824DAE15-3628-4346-947E-C33FA46AADE6"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:barracuda:email_security_gateway_400_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4A9B9E0B-F8D4-4626-AD39-BD525D638693", "versionEndIncluding": "9.2.0.006", "versionStartIncluding": "5.1.3.001"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:barracuda:email_security_gateway_400:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "ACD3DD62-D690-47F9-8416-61AD78B33699"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:barracuda:email_security_gateway_600_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "83D228EA-35C8-4B6E-9D22-CF0F7C20362B", "versionEndIncluding": "9.2.0.006", "versionStartIncluding": "5.1.3.001"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:barracuda:email_security_gateway_600:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "6C507D86-2E68-44A4-A31C-EEF9A6BBEE54"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:barracuda:email_security_gateway_800_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8ADAC6B0-DE92-41F6-B8B1-1C830BB70C24", "versionEndIncluding": "9.2.0.006", "versionStartIncluding": "5.1.3.001"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:barracuda:email_security_gateway_800:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "74D999D5-6CE5-49F7-A0C5-0B44704FEE45"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:barracuda:email_security_gateway_900_firmware:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C5A27A43-E632-4C8A-A9F8-49C6E091E7ED", "versionEndIncluding": "9.2.0.006", "versionStartIncluding": "5.1.3.001"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:barracuda:email_security_gateway_900:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "FFA6EA4B-B0FF-437B-A48E-F11D0CD5EB2B"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve-coordination@google.com", "cisaRequiredAction": "Apply updates per vendor instructions.", "cisaVulnerabilityName": "Barracuda Networks ESG Appliance Improper Input Validation Vulnerability"}
