The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access.","A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker...","2020-11-18T19:15:12.697","2020-12-02T16:57:00.417",6.5,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:L\u002FI:L\u002FA:N",{"CVSSMetricV31":15,"CVSSMetricV30":29,"CVSSMetricV2":36,"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":22,"IntegrityImpact":22,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":23,"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","MEDIUM",null,3.9,2.5,[30],{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":27,"ImpactScore":28},"ykramarz@cisco.com","Secondary",{"Version":34,"VectorString":35,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":22,"IntegrityImpact":22,"AvailabilityImpact":23,"BaseScore":12,"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:U\u002FC:L\u002FI:L\u002FA:N",[37],{"Source":17,"Type":18,"CVSSData":38,"BaseSeverity":25,"ExploitabilityScore":43,"ImpactScore":44,"ACInsufInfo":26,"ObtainAllPrivilege":26,"ObtainUserPrivilege":26,"ObtainOtherPrivilege":26,"UserInteractionRequired":26},{"Version":39,"VectorString":40,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":41,"IntegrityImpact":41,"AvailabilityImpact":23,"BaseScore":42,"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:P\u002FI:P\u002FA:N","PARTIAL",6.4,10,4.9,0.01378,[45,45,45,45,45,45,45],"Medium",[49,54],{"vendor":50,"product":51,"version":52,"criteria":53,"vulnerable":4},"cisco","expressway","*","cpe:2.3:a:cisco:expressway:*:*:*:*:*:*:*:*",{"vendor":50,"product":55,"version":52,"criteria":56,"vulnerable":4},"telepresence_video_communication_server","cpe:2.3:a:cisco:telepresence_video_communication_server:*:*:*:*:*:*:*:*",2,[59],{"url":60,"source":61,"tags":62},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-Expressway-8J3yZ7hV","Cisco",[63],"Vendor Advisory",1,[66,74],{"id":67,"name":68,"description":69,"extendedDescription":70,"status":71,"abstraction":72,"structure":73},"CWE-269","Improper Privilege Management","The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.","","Draft","Class","Simple",{"id":75,"name":76,"description":77,"extendedDescription":78,"status":79,"abstraction":80,"structure":73},"CWE-284","Improper Access Control","The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.","Access control involves the use of several protection mechanisms such as:\nWhen any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc.\nThere are two distinct behaviors that can introduce access control weaknesses:","Incomplete","Pillar",false,[],{"title":84,"metaDescription":85,"keywords":86,"canonicalUrl":87,"structuredData":88},"What is CVE-2020-3482?
