The vulnerabilities are due to insufficient validation of user-supplied input and improper boundary checks when reading data into an internal buffer. An attacker could exploit these vulnerabilities by sending malicious requests to the web management interface of an affected device. Depending on the configuration of the affected switch, the malicious requests must be sent via HTTP or HTTPS.","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":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-119"],"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":0.25944,"percentile":0.97985,"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 25.9%, higher than 98% of all known CVEs.
