{"cve":"CVE-2017-11580","nvd":{"published":"2019-07-02T21:15:10.010","modified":"2026-06-17T01:02:02.673","status":"Modified","description":"Blipcare Wifi blood pressure monitor BP700 10.1 devices allow memory corruption that results in Denial of Service. When connected to the \"Blip\" open wireless connection provided by the device, if a large string is sent as a part of the HTTP request in any part of the HTTP headers, the device could become completely unresponsive. Presumably this happens as the memory footprint provided to this device is very small. According to the specs from Rezolt, the Wi-Fi module only has 256k of memory. As a result, an incorrect string copy operation using either memcpy, strcpy, or any of their other variants could result in filling up the memory space allocated to the function executing and this would result in memory corruption. To test the theory, one can modify the demo application provided by the Cypress WICED SDK and introduce an incorrect \"memcpy\" operation and use the compiled application on the evaluation board provided by Cypress semiconductors with exactly the same Wi-Fi SOC. The results were identical where the device would completely stop responding to any of the ping or web requests.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-399"],"references":["http://packetstormsecurity.com/files/153225/Blipcare-Clear-Text-Communication-Memory-Corruption.html","https://github.com/ethanhunnt/IoT_vulnerabilities/blob/master/Blipcare_sec_issues.pdf","https://seclists.org/bugtraq/2019/Jun/8","http://packetstormsecurity.com/files/153225/Blipcare-Clear-Text-Communication-Memory-Corruption.html","https://github.com/ethanhunnt/IoT_vulnerabilities/blob/master/Blipcare_sec_issues.pdf"],"products":["blipcare:wi-fi_blood_pressure_monitor_firmware"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2017-11580","score":0.01431,"percentile":0.73047,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
