{"schemaVersion":3,"id":"CVE-2025-68137","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"EVerest is an EV charging software stack. Prior to version 2025.10.0, an integer overflow occurring in `SdpPacket::parse_header()` allows the current buffer length to be set to 7 after a complete header of size 8 has been read. The remaining length to read is computed using the current length subtracted by the header length which results in a negative value. This value is then interpreted as `SIZE_MAX` (or slightly less) because the expected type of the argument is `size_t`. Depending on whether the server is plain TCP or TLS, this leads to either an infinite loop or a stack buffer overflow. Version 2025.10.0 fixes the issue.","dates":{"published":"2026-01-21T19:20:09.059Z","modified":"2026-01-21T19:51:26.058Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.4,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.4,"severity":"high","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.3,"severity":"high","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01297,"percentile":0.69954,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0.209,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.01088},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00975,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00975,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00975,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00975,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01297,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01297,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01297,"percentile":0.69954}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01088,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01268,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score"
