{"id":"CVE-2019-1914","aliases":["EUVD-2019-10471","GHSA-pc87-g4cg-ch62"],"status":"published","title":"Cisco Small Business 220 Series Smart Switches Command Injection Vulnerability","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.","severity":{"version":"3.0","score":7.2,"vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.24852,"percentile":0.9792,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":false},"cwes":["CWE-20"],"published":"2019-08-07T05:50:11Z","modified":"2026-06-17T02:29:35Z","exploits":[{"source":"exploitdb","id":"EDB-47442","title":"Cisco Small Business 220 Series - Multiple Vulnerabilities","type":"remote","platform":"hardware","date":"2019-09-30","url":"https://www.exploit-db.com/exploits/47442"}],"products":[{"vendor":"cisco","product":"cisco small business 220 series smart plus switches"},{"vendor":"cisco","product":"sf-220-24_firmware"},{"vendor":"cisco","product":"sf220-24p_firmware"},{"vendor":"cisco","product":"sf220-48_firmware"},{"vendor":"cisco","product":"sf220-48p_firmware"},{"vendor":"cisco","product":"sg220-26_firmware"},{"vendor":"cisco","product":"sg220-26p_firmware"},{"vendor":"cisco","product":"sg220-28_firmware"},{"vendor":"cisco","product":"sg220-28mp_firmware"},{"vendor":"cisco","product":"sg220-50_firmware"},{"vendor":"cisco","product":"sg220-50p_firmware"},{"vendor":"cisco","product":"sg220-52_firmware"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190806-sb220-inject","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://packetstormsecurity.com/files/154667/Realtek-Managed-Switch-Controller-RTL83xx-Stack-Overflow.html","tags":["x_refsource_MISC","x_transferred"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1914"},{"url":"https://github.com/advisories/GHSA-pc87-g4cg-ch62"}],"sources":{"cve":[{"id":"CVE-2019-1914","title":"Cisco Small Business 220 Series Smart Switches Command Injection Vulnerability","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.
