{"schemaVersion":3,"id":"CVE-2020-15795","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus Source Code (Versions including affected DNS modules), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). The DNS domain name label parsing functionality does not properly validate the names in DNS-responses. The parsing of malformed responses could result in a write past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to execute code in the context of the current process or cause a denial-of-service condition.","dates":{"published":"2021-04-22T20:42:19.000Z","modified":"2024-08-04T13:30:21.684Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":6.8,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.06366,"percentile":0.93586,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.06366},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.06366,"percentile":0.93586}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.06366,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0
