By sending a signal to the CLI process, undocumented functionality is triggered. Specifically, a menu can be triggered by sending the SIGQUIT signal to the CLI application (e.g., through CTRL+\\ via SSH). The access control check for this menu does work and prohibits accessing the menu, which contains \"Password recovery for specific user\" options. The menu is believed to be accessible using a serial console."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2019-15804", "ASSIGNER": "cve@mitre.org"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 5.0, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:N/C:N/I:P/A:N", "authentication": "NONE", "integrityImpact": "PARTIAL", "accessComplexity": "LOW", "availabilityImpact": "NONE", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 10.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 3.9}}, "publishedDate": "2019-11-14T21:15Z", "configurations": {"nodes": [{"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-8_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahh.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-8:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-8hp_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahi.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-8hp:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-10hp_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aazi.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-10hp:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-16_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahj.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-16:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-24e_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahk.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-24e:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-24_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahl.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-24:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-24hp_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahm.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-24hp:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-48_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aahn.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-48:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:zyxel:gs1900-48hp_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2.50\\(aaho.0\\)c0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:zyxel:gs1900-48hp:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2020-08-24T17:37Z"}
