An attacker could exploit this vulnerability by sending a crafted SNMP packet to the affected device. \r\n\r\n\r\n\r\nThe vulnerability is due to a buffer overflow in the affected code area. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3). The attacker must know the SNMP read only community string (SNMP version 2c or earlier) or the user credentials (SNMPv3). An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system.\r\n\r\n\r\n\r\nOnly traffic directed to the affected system can be used to exploit this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-119"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170629-snmp","http://www.securityfocus.com/bid/99345","http://www.securitytracker.com/id/1038808","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170629-snmp","https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2017-6739"],"products":["cisco:ios","cisco:ios_xe"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-6739","score":0.10855,"percentile":0.95859,"date":"2026-10-31"},"kev":{"cve":"CVE-2017-6739","date_added":"2022-03-03","due_date":"2022-03-24","vendor":"Cisco","product":"IOS and IOS XE Software","known_ransomware":false},"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
