The vulnerability is due to the insufficient validation of data supplied by external devices to the web-based management interface of an affected PCA device. An attacker in control of devices integrated with an affected PCA device could exploit this vulnerability by using crafted data in certain fields of the controlled devices. A successful exploit could allow the attacker to execute arbitrary script code in the context of the PCA web-based management interface or allow the attacker to access sensitive browser-based information.","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-79"],"references":["http://www.securityfocus.com/bid/108148","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-pca-xss","http://www.securityfocus.com/bid/108148","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-pca-xss"],"products":["cisco:prime_collaboration_assurance"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2019-1856","score":0.01067,"percentile":0.64801,"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).
