The vulnerability is due to incomplete input validation of the 802.11 GAS frames that are processed by an affected device. An attacker could exploit this vulnerability by sending a crafted 802.11 GAS frame over the air to an access point (AP), and that frame would then be relayed to the affected WLC. Also, an attacker with Layer 3 connectivity to the WLC could exploit this vulnerability by sending a malicious 802.11 GAS payload in a Control and Provisioning of Wireless Access Points (CAPWAP) packet to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS.","A vulnerability in the 802.11 Generic Advertisement Service (GAS) frame processing function of Cisco Wireless LAN Controller (WLC) Software could allow an un...","2020-04-15T21:15:36.183","2020-04-29T15:33:15.137",7.5,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:N\u002FI:N\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":29,"CVSSMetricV2":39,"CVSSMetricV40":26},[16],{"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,[30],{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":27,"ImpactScore":38},"ykramarz@cisco.com","Secondary",{"Version":34,"VectorString":35,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":36,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":25,"BaseScore":37,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.0","CVSS:3.0\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:C\u002FC:N\u002FI:N\u002FA:H","CHANGED",8.6,4,[40],{"Source":17,"Type":18,"CVSSData":41,"BaseSeverity":46,"ExploitabilityScore":47,"ImpactScore":48,"ACInsufInfo":26,"ObtainAllPrivilege":26,"ObtainUserPrivilege":26,"ObtainOtherPrivilege":26,"UserInteractionRequired":26},{"Version":42,"VectorString":43,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":44,"BaseScore":45,"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,"MEDIUM",10,2.9,0.01274,[49,49,49,49,49,49,49],"High",[53,58,61,65,68,70],{"vendor":54,"product":55,"version":56,"criteria":57,"vulnerable":4},"cisco","5508_wireless_controller_firmware","8.5\\(151.0\\)","cpe:2.3:o:cisco:5508_wireless_controller_firmware:8.5\\(151.0\\):*:*:*:*:*:*:*",{"vendor":54,"product":55,"version":59,"criteria":60,"vulnerable":4},"8.10\\(204.92\\)","cpe:2.3:o:cisco:5508_wireless_controller_firmware:8.10\\(204.92\\):*:*:*:*:*:*:*",{"vendor":54,"product":62,"version":63,"criteria":64,"vulnerable":4},"5508_wireless_controller","-","cpe:2.3:h:cisco:5508_wireless_controller:-:*:*:*:*:*:*:*",{"vendor":54,"product":66,"version":56,"criteria":67,"vulnerable":4},"5520_wireless_controller_firmware","cpe:2.3:o:cisco:5520_wireless_controller_firmware:8.5\\(151.0\\):*:*:*:*:*:*:*",{"vendor":54,"product":66,"version":59,"criteria":69,"vulnerable":4},"cpe:2.3:o:cisco:5520_wireless_controller_firmware:8.10\\(204.92\\):*:*:*:*:*:*:*",{"vendor":54,"product":71,"version":63,"criteria":72,"vulnerable":4},"5520_wireless_controller","cpe:2.3:h:cisco:5520_wireless_controller:-:*:*:*:*:*:*:*",6,[75],{"url":76,"source":77,"tags":78},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-wlc-gas-dos-8FsE3AWH","Cisco",[79],"Vendor Advisory",1,[82],{"id":83,"name":84,"description":85,"extendedDescription":86,"status":87,"abstraction":88,"structure":89},"CWE-119","Improper Restriction of Operations within the Bounds of a Memory Buffer","The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary.
