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.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","base_score":9.8,"base_severity":"CRITICAL","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"NONE","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-20","CWE-77"],"in_kev":true,"kev_date_added":"2023-05-26","kev_ransomware":false,"epss_score":0.86841,"epss_percentile":0.99744,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":false,"grant_access":"USER","caps":["CODE_EXEC"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-09-18T10:26:17.880410+00:00","first_seen":"2023-05-24T19:15:09.363000+00:00","kev_first_seen":"2023-05-26T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":null,"vendors":["barracuda"],"products":["email_security_gateway_300","email_security_gateway_300_firmware","email_security_gateway_400","email_security_gateway_400_firmware","email_security_gateway_600","email_security_gateway_600_firmware","email_security_gateway_800","email_security_gateway_800_firmware","email_security_gateway_900","email_security_gateway_900_firmware"],"affected":[{"vendor":"barracuda","product":"email_security_gateway_300_firmware","ranges":["≥ 5.1.3.001 and ≤ 9.2.0.006"]},{"vendor":"barracuda","product":"email_security_gateway_400_firmware","ranges":["≥ 5.1.3.001 and ≤ 9.2.0.006"]},{"vendor":"barracuda","product":"email_security_gateway_600_firmware","ranges":["≥ 5.1.3.001 and ≤ 9.2.0.006"]},{"vendor":"barracuda","product":"email_security_gateway_800_firmware","ranges":["≥ 5.1.3.001 and ≤ 9.2.0.006"]},{"vendor":"barracuda","product":"email_security_gateway_900_firmware","ranges":["≥ 5.1.3.001 and ≤ 9.2.0.006"]}]}
