An attacker could exploit this vulnerability by connecting through an affected device to a malicious server and receiving malformed HTTP responses. A successful exploit could allow the attacker to bypass an explicit block rule and receive traffic that should have been rejected by the device."}],"affected":[{"vendor":"Cisco","product":"Cisco Secure Web Appliance","versions":[{"version":"11.8.0-414","status":"affected"},{"version":"11.8.1-023","status":"affected"},{"version":"11.8.3-018","status":"affected"},{"version":"11.8.3-021","status":"affected"},{"version":"12.0.1-268","status":"affected"},{"version":"12.0.3-007","status":"affected"},{"version":"12.5.2-007","status":"affected"},{"version":"12.5.1-011","status":"affected"},{"version":"12.5.4-005","status":"affected"},{"version":"12.5.5-004","status":"affected"},{"version":"14.5.0-498","status":"affected"},{"version":"14.0.3-014","status":"affected"},{"version":"14.0.2-012","status":"affected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Improper Input Validation","type":"cwe","cweId":"CWE-20"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-bypass-bwBfugek","name":"cisco-sa-wsa-bypass-bwBfugek"}],"metrics":[{"format":"cvssV3_1","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"}}],"exploits":[{"lang":"en","value":"The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerabilities that are described in this advisory."}],"source":{"advisory":"cisco-sa-wsa-bypass-bwBfugek","discovery":"INTERNAL","defects":["CSCwc54898"]}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T02:31:59.019Z"},"title":"CVE Program Container","references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wsa-bypass-bwBfugek","name":"cisco-sa-wsa-bypass-bwBfugek","tags":["x_transferred"]}]}]}}
