This vulnerability is due to insufficient error handling during packet processing. An attacker could exploit this vulnerability by sending a high and sustained rate of crafted TCP traffic to the IOx web server on an affected device. A successful exploit could allow the attacker to cause the IOx web server to stop processing requests, resulting in a DoS condition.","A vulnerability in the Cisco IOx Application Framework of Cisco 809 Industrial Integrated Services Routers (Industrial ISRs), Cisco 829 Industrial ISRs, Cisc...","2021-03-24T20:15:15.777","2023-11-07T03:28:22.057",7.5,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:N\u002FI:N\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":26,"CVSSMetricV2":37,"CVSSMetricV40":26},[16,29],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":27,"ImpactScore":28},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":25,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":25,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.1","NETWORK","LOW","NONE","UNCHANGED","HIGH",null,3.9,3.6,{"Source":30,"Type":31,"CVSSData":32,"ExploitabilityScore":27,"ImpactScore":36},"d1c1063e-7a18-46af-9102-31f8928bc633","Secondary",{"Version":20,"VectorString":33,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":22,"BaseScore":34,"BaseSeverity":35,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":22,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:N\u002FI:N\u002FA:L",5.3,"MEDIUM",1.4,[38],{"Source":17,"Type":18,"CVSSData":39,"BaseSeverity":35,"ExploitabilityScore":44,"ImpactScore":45,"ACInsufInfo":26,"ObtainAllPrivilege":26,"ObtainUserPrivilege":26,"ObtainOtherPrivilege":26,"UserInteractionRequired":26},{"Version":40,"VectorString":41,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":42,"BaseScore":43,"BaseSeverity":26,"Exploitability":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"CollateralDamagePotential":26,"TargetDistribution":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"EnvironmentalScore":26},"2.0","AV:N\u002FAC:L\u002FAu:N\u002FC:N\u002FI:N\u002FA:P","PARTIAL",5,10,2.9,0.01351,[48,48,46,46,46,46,46],0.01305,"High",[51,56,60,63,66,69,72],{"vendor":52,"product":53,"version":54,"criteria":55,"vulnerable":4},"cisco","ios","*","cpe:2.3:a:cisco:ios:*:*:*:*:*:*:*:*",{"vendor":52,"product":57,"version":58,"criteria":59,"vulnerable":4},"809_industrial_integrated_services_router","-","cpe:2.3:h:cisco:809_industrial_integrated_services_router:-:*:*:*:*:*:*:*",{"vendor":52,"product":61,"version":58,"criteria":62,"vulnerable":4},"829_industrial_integrated_services_router","cpe:2.3:h:cisco:829_industrial_integrated_services_router:-:*:*:*:*:*:*:*",{"vendor":52,"product":64,"version":54,"criteria":65,"vulnerable":4},"cgr1000_firmware","cpe:2.3:o:cisco:cgr1000_firmware:*:*:*:*:*:*:*:*",{"vendor":52,"product":67,"version":58,"criteria":68,"vulnerable":4},"cgr1000","cpe:2.3:h:cisco:cgr1000:-:*:*:*:*:*:*:*",{"vendor":52,"product":70,"version":54,"criteria":71,"vulnerable":4},"ic3000_industrial_compute_gateway_firmware","cpe:2.3:o:cisco:ic3000_industrial_compute_gateway_firmware:*:*:*:*:*:*:*:*",{"vendor":52,"product":73,"version":58,"criteria":74,"vulnerable":4},"ic3000_industrial_compute_gateway","cpe:2.3:h:cisco:ic3000_industrial_compute_gateway:-:*:*:*:*:*:*:*",7,[77],{"url":78,"source":79,"tags":80},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-iox-dos-4Fgcjh6","Cisco",[81],"Vendor Advisory",1,[84],{"id":85,"name":86,"description":87,"extendedDescription":88,"status":89,"abstraction":90,"structure":91},"CWE-400","Uncontrolled Resource Consumption","The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.","Limited resources include memory, file system storage, database connection pool entries, and CPU.
