The file types that can be shown depend on the user context in which the exploitable application is running. If the user is root a full compromise of the server - including confidential or sensitive files - would be possible. XXE can also be used to attack the availability of the server via denial of service as the references within a xml document can trivially trigger an amplification attack.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:H","score":7.3},"cwes":["CWE-611"],"references":["http://www.debian.org/security/2017/dsa-3864","http://www.securityfocus.com/bid/97947","https://www.tenable.com/security/tns-2021-14","https://xmlgraphics.apache.org/security.html","http://www.debian.org/security/2017/dsa-3864"],"products":["apache:formatting_objects_processor"],"source":"nvd","synced_at":"2026-10-19T20:42:09.859288039+00:00"},"epss":{"cve":"CVE-2017-5661","score":0.02519,"percentile":0.84838,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5hg8-r9vq-gjqp","url":"https://osv.dev/vulnerability/GHSA-5hg8-r9vq-gjqp","summary":"Improper Restriction of XML External Entity Reference in Apache FOP","modified":"2023-11-08T03:59:23.103292Z","packages":[{"ecosystem":"Maven","name":"org.apache.xmlgraphics:fop","purl":"pkg:maven/org.apache.xmlgraphics/fop","ranges":["<2.2"],"fixed":["2.2"]}]}],"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).
