The vulnerability is due to improper validation of HTTPS packets. An attacker could exploit this vulnerability by sending a malformed HTTPS packet to the management web interface of the affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a denial of service (DoS) condition.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-119"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-sbss-memcorrupt","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190703-sbss-memcorrupt"],"products":["cisco:esw2-350g52dc_firmware","cisco:esw2-550x48dc_firmware","cisco:sf200-24_firmware","cisco:sf200-24p_firmware","cisco:sf200-48_firmware","cisco:sf200-48p_firmware","cisco:sf300-08_firmware","cisco:sf300-24_firmware","cisco:sf300-24mp_firmware","cisco:sf300-24p_firmware","cisco:sf300-24pp_firmware","cisco:sf300-48_firmware","cisco:sf300-48p_firmware","cisco:sf300-48pp_firmware","cisco:sf302-08_firmware","cisco:sf302-08mp_firmware","cisco:sf302-08mpp_firmware","cisco:sf302-08p_firmware","cisco:sf302-08pp_firmware","cisco:sf500-24_firmware","cisco:sf500-24mp_firmware","cisco:sf500-24p_firmware","cisco:sf500-48_firmware","cisco:sf500-48mp_firmware","cisco:sf500-48p_firmware","cisco:sg200-18_firmware","cisco:sg200-26_firmware","cisco:sg200-26p_firmware","cisco:sg200-50_firmware","cisco:sg200-50p_firmware","cisco:sg300-10_firmware","cisco:sg300-10mp_firmware","cisco:sg300-10mpp_firmware","cisco:sg300-10p_firmware","cisco:sg300-10pp_firmware","cisco:sg300-10sfp_firmware","cisco:sg300-20_firmware","cisco:sg300-28_firmware","cisco:sg300-28mp_firmware","cisco:sg300-28p_firmware","cisco:sg300-28pp_firmware","cisco:sg300-28sfp_firmware","cisco:sg300-52_firmware","cisco:sg300-52mp_firmware","cisco:sg300-52p_firmware","cisco:sg500-28_firmware","cisco:sg500-28mpp_firmware","cisco:sg500-28p_firmware","cisco:sg500-52_firmware","cisco:sg500-52mp_firmware"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2019-1892","score":0.01772,"percentile":0.78155,"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).
