The vulnerability is due to improper input validation of the parameters of an HTTP request. An attacker could exploit this vulnerability by intercepting a user's HTTP request and modifying it into a request that causes the web interface to redirect the user to a specific malicious URL. This type of vulnerability is known as an open redirect attack and is used in phishing attacks that get users to unknowingly visit malicious sites.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-601"],"references":["http://www.securityfocus.com/bid/109288","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190717-sbss-redirect","http://www.securityfocus.com/bid/109288","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190717-sbss-redirect"],"products":["cisco:sf200-24_firmware","cisco:sf200-24fp_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:sf500-24p_firmware","cisco:sf500-48_firmware","cisco:sf500-48p_firmware","cisco:sg200-08_firmware","cisco:sg200-08p_firmware","cisco:sg200-10fp_firmware","cisco:sg200-18_firmware","cisco:sg200-26_firmware","cisco:sg200-26fp_firmware","cisco:sg200-26p_firmware","cisco:sg200-50_firmware","cisco:sg200-50fp_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:sg300-52_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"],"source":"nvd","synced_at":"2026-10-19T20:58:11.797917892+00:00"},"epss":{"cve":"CVE-2019-1943","score":0.09687,"percentile":0.95505,"date":"2026-11-01"},"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).
