{"id":"CVE-2023-20126","state":"PUBLISHED","title":"Cisco SPA112 2-Port Phone Adapters Remote Command Execution Vulnerability","description":"A vulnerability in the web-based management interface of Cisco SPA112 2-Port Phone Adapters could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to a missing authentication process within the firmware upgrade function. An attacker could exploit this vulnerability by upgrading an affected device to a crafted version of firmware. A successful exploit could allow the attacker to execute arbitrary code on the affected device with full privileges. Cisco has not released firmware updates to address this vulnerability.","publishedAt":"2023-05-04T00:00:00.000Z","updatedAt":"2024-10-28T16:29:55.803Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Small Business IP Phones"],"affected":[{"vendor":"Cisco","product":"Cisco Small Business IP Phones","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-spa-unauth-upgrade-UqhyTWW"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/20xxx/CVE-2023-20126.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-20126","state":"PUBLISHED","datePublished":"2023-05-04T00:00:00.000Z","dateUpdated":"2024-10-28T16:29:55.803Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2022-10-27T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco SPA112 2-Port Phone Adapters Remote Command Execution Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the web-based management interface of Cisco SPA112 2-Port Phone Adapters could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device.
