{"id":"CVE-2023-20030","aliases":["EUVD-2023-24209","GHSA-25m5-5hwm-rp7r"],"status":"published","title":"Cisco Identity Services Engine XML External Entity Injection Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to access sensitive information, conduct a server-side request forgery (SSRF) attack through an affected device, or negatively impact the responsiveness of the web-based management interface itself. This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of confidential information. A successful exploit could also cause the web application to perform arbitrary HTTP requests on behalf of the attacker or consume memory resources to reduce the availability of the web-based management interface. To successfully exploit this vulnerability, an attacker would need valid Super Admin or Policy Admin credentials.","severity":{"version":"3.1","score":6,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.0075,"percentile":0.55285,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-611"],"published":"2023-04-05T00:00:00Z","modified":"2026-06-17T05:29:19Z","products":[{"vendor":"cisco","product":"cisco identity services engine software"},{"vendor":"cisco","product":"identity_services_engine"}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-xxe-inj-GecEHY58","tags":["vendor-advisory","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-20030"},{"url":"https://github.com/advisories/GHSA-25m5-5hwm-rp7r"}],"sources":{"cve":[{"id":"CVE-2023-20030","title":"Cisco Identity Services Engine XML External Entity Injection Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to access sensitive information, conduct a server-side request forgery (SSRF) attack through an affected device, or negatively impact the responsiveness of the web-based management interface itself.
