{"id":"CVE-2019-1914","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-1914","generatedAt":"2026-11-05T02:46:48.971Z","title":"A vulnerability in the web management interface of Cisco Small Business 220 Series Smart Switches could allow an authenticated, remote attacker to perform a command injection attack.","description":"A vulnerability in the web management interface of Cisco Small Business 220 Series Smart Switches could allow an authenticated, remote attacker to perform a command injection attack. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious request to certain parts of the web management interface. To send the malicious request, the attacker needs a valid login session in the web management interface as a privilege level 15 user. Depending on the configuration of the affected switch, the malicious request must be sent via HTTP or HTTPS. A successful exploit could allow the attacker to execute arbitrary shell commands with the privileges of the root user.","published":"2019-08-07T06:15:12.000Z","lastModified":"2026-06-17T02:29:36.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":7.2,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":["cisco/sf-220-24 firmware","cisco/sf220-24p firmware","cisco/sf220-48 firmware","cisco/sf220-48p firmware","cisco/sg220-26 firmware","cisco/sg220-26p firmware","cisco/sg220-28 firmware","cisco/sg220-28mp firmware","cisco/sg220-50 firmware","cisco/sg220-50p firmware","cisco/sg220-52 firmware"],"epss":{"score":0.24852,"percentile":0.97909,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2019-09-30","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":47442,"kind":"exploit","title":"Cisco Small Business 220 Series - Multiple Vulnerabilities","url":"https://www.exploit-db.com/exploits/47442","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/remote/47442.py","file":"exploits/hardware/remote/47442.py","published":"2019-09-30","added":"2019-09-30","updated":"2019-09-30","author":"bashis","type":"remote","platform":"hardware","port":null,"verified":false,"codes":["CVE-2019-1914","CVE-2019-1913","CVE-2019-1912"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 24.9%, higher than 98% of all known CVEs.
