To exploit this vulnerability, the attacker must have valid credentials on the system.\r\n\r\nThis vulnerability is due to insufficient input validation of the HTTPS URL by the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to write arbitrary files to the host system.\r\nCisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-24"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-pi-epnm-path-trav-zws324yn","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sna-xss-NXOxDhRQ"],"products":["cisco:evolved_programmable_network_manager","cisco:prime_infrastructure"],"source":"nvd","synced_at":"2026-10-19T21:57:07.693694550+00:00"},"epss":{"cve":"CVE-2022-20656","score":0.01694,"percentile":0.77127,"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).
