{"schemaVersion":3,"id":"CVE-2023-25187","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An issue was discovered on NOKIA Airscale ASIKA Single RAN devices before 21B. Nokia Single RAN commissioning procedures do not change (factory-time installed) default SSH public/private key values that are specific to a network operator. As a result, the CSP internal BTS network SSH server (disabled by default) continues to apply the default SSH public/private key values. These keys don't give access to BTS, because service user authentication is username/password-based on top of SSH. Nokia factory installed default SSH keys are meant to be changed from operator-specific values during the BTS deployment commissioning phase. However, before the 21B release, BTS commissioning manuals did not provide instructions to change default SSH keys (to BTS operator-specific values). This leads to a possibility for malicious operations staff (inside a CSP network) to attempt MITM exploitation of BTS service user access, during the moments that SSH is enabled for Nokia service personnel to perform troubleshooting activities.","dates":{"published":"2023-06-16T00:00:00.000Z","modified":"2024-12-12T20:38:02.588Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.3,"severity":"medium","vector":"CVSS:3.1/AC:H/AV:L/A:H/C:H/I:H/PR:H/S:U/UI:R","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7,"severity":"high","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00956,"percentile":0.60778,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00956},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00956,"percentile":0.60778}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00956,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00
