The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).","2020-02-05T18:15:00Z",{"cvss_v2.0":10,"cvss_v3.1":18},{"version":11,"baseScore":12,"accessVector":13,"vectorString":14,"authentication":15,"integrityImpact":16,"accessComplexity":17,"availabilityImpact":16,"confidentialityImpact":16},"2.0",8.3,"ADJACENT_NETWORK","AV:A\u002FAC:L\u002FAu:N\u002FC:C\u002FI:C\u002FA:C","NONE","COMPLETE","LOW",{"scope":19,"version":20,"baseScore":21,"attackVector":13,"baseSeverity":22,"vectorString":23,"integrityImpact":22,"userInteraction":15,"attackComplexity":17,"availabilityImpact":22,"privilegesRequired":15,"confidentialityImpact":22},"UNCHANGED","3.1",8.8,"HIGH","CVSS:3.1\u002FAV:A\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",false,[26],"CWE-20",[28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81],"cpe:2.3:o:cisco:ip_phone_6821_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7821_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_conference_phone_8832:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_6851_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8841:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7861_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8841_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8845:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8811_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7811_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8845_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_6841:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_conference_phone_7832:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:unified_ip_conference_phone_8831:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_6871_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8865_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:unified_ip_conference_phone_8831_for_third-party_call_control:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7811_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:unified_ip_conference_phone_8831_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:wireless_ip_phone_8821-ex:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_conference_phone_7832_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_6851:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8861_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7841_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8811:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7821_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_6861:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_conference_phone_8832_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7861_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_7841:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_7821:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8851_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:wireless_ip_phone_8821_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8811_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_conference_phone_8832_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:wireless_ip_phone_8821-ex_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8865:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_6871:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8861:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_7861:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_6821:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8841_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8865_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:unified_ip_conference_phone_8831_for_third-party_call_control_firmware:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_7811:-:*:*:*:*:*:*:*","cpe:2.3:h:cisco:wireless_ip_phone_8821:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_7841_with_multiplatform_firmware:*:*:*:*:*:*:*:*","cpe:2.3:h:cisco:ip_phone_8851:-:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8851_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_conference_phone_7832_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_6861_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8845_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_6841_firmware:*:*:*:*:*:*:*:*","cpe:2.3:o:cisco:ip_phone_8861_with_multiplatform_firmware:*:*:*:*:*:*:*:*",[83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136],"Cisco
