{"cve":"CVE-2018-0453","nvd":{"published":"2018-10-05T14:29:03.340","modified":"2026-08-11T19:33:44.513","status":"Modified","description":"A vulnerability in the Sourcefire tunnel control channel protocol in Cisco Firepower System Software running on Cisco Firepower Threat Defense (FTD) sensors could allow an authenticated, local attacker to execute specific CLI commands with root privileges on the Cisco Firepower Management Center (FMC), or through Cisco FMC on other Firepower sensors and devices that are controlled by the same Cisco FMC. To send the commands, the attacker must have root privileges for at least one affected sensor or the Cisco FMC. The vulnerability exists because the affected software performs insufficient checks for certain CLI commands, if the commands are executed via a Sourcefire tunnel connection. An attacker could exploit this vulnerability by authenticating with root privileges to a Firepower sensor or Cisco FMC, and then sending specific CLI commands to the Cisco FMC or through the Cisco FMC to another Firepower sensor via the Sourcefire tunnel connection. A successful exploit could allow the attacker to modify device configurations or delete files on the device that is running Cisco FMC Software or on any Firepower device that is managed by Cisco FMC.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.2},"cwes":["CWE-78","CWE-264"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-fp-cmd-injection","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-fp-cmd-injection"],"products":["cisco:secure_firewall_threat_defense"],"source":"nvd","synced_at":"2026-10-19T20:53:14.491561039+00:00"},"epss":{"cve":"CVE-2018-0453","score":0.00411,"percentile":0.35342,"date":"2026-10-31"},"kev":null,"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).
