{"cve":"CVE-2019-1700","nvd":{"published":"2019-02-21T21:29:00.313","modified":"2026-06-17T02:29:04.717","status":"Modified","description":"A vulnerability in field-programmable gate array (FPGA) ingress buffer management for the Cisco Firepower 9000 Series with the Cisco Firepower 2-port 100G double-width network module (PID: FPR9K-DNM-2X100G) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. Manual intervention may be required before a device will resume normal operations. The vulnerability is due to a logic error in the FPGA related to the processing of different types of input packets. An attacker could exploit this vulnerability by being on the adjacent subnet and sending a crafted sequence of input packets to a specific interface on an affected device. A successful exploit could allow the attacker to cause a queue wedge condition on the interface. When a wedge occurs, the affected device will stop processing any additional packets that are received on the wedged interface. Version 2.2 is affected.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","score":6.1},"cwes":["CWE-399"],"references":["http://www.securityfocus.com/bid/107105","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-firpwr-dos","http://www.securityfocus.com/bid/107105","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-firpwr-dos"],"products":["cisco:firepower_9000_firmware"],"source":"nvd","synced_at":"2026-10-19T20:54:46.948512734+00:00"},"epss":{"cve":"CVE-2019-1700","score":0.00501,"percentile":0.42912,"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).
