{"schemaVersion":3,"id":"CVE-2021-1132","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in the API subsystem and in the web-management interface of Cisco Network Services Orchestrator (NSO) could allow an unauthenticated, remote attacker to access sensitive data.\nThis vulnerability exists because the web-management interface and certain HTTP-based APIs do not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.","dates":{"published":"2024-11-18T15:42:08.936Z","modified":"2024-11-18T16:36:46.502Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/RL:X/RC:X/E:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01629,"percentile":0.75797,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.01629},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01629,"percentile":0.75797}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-10-10T00:00:
