The vulnerabilities are due to improper input validation of the parameters of an HTTP request. An attacker could exploit these vulnerabilities by intercepting an HTTP request and modifying it to redirect a user to a specific malicious URL. A successful exploit could allow the attacker to redirect a user to a malicious web page or to obtain sensitive browser-based information. This type of attack is commonly referred to as an open redirect attack and is used in phishing attacks to get users to unknowingly visit malicious sites.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-601"],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sma-opn-rdrct-yPPMdsMQ","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sma-opn-rdrct-yPPMdsMQ"],"products":["cisco:content_security_management_appliance"],"source":"nvd","synced_at":"2026-10-19T21:04:18.695612450+00:00"},"epss":{"cve":"CVE-2020-3178","score":0.00843,"percentile":0.57949,"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).
