Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34706 in the wild and no public exploit code.\n\nAffected product: Cisco Identity Services Engine. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-34706/ (Markdown: https://insights.sbomify.com/CVE-2021-34706/index.md)","id":"CVE-2021-34706","markdown":"https://insights.sbomify.com/CVE-2021-34706/index.md","name":"CVE-2021-34706","record":{"aliases":["GHSA-gjrq-r2pc-24vf"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Identity Services Engine","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit XXE in Cisco ISE to read local files or perform SSRF, leading to information disclosure.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"identity_services_engine","vendor":"cisco"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"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 or conduct a server-side request forgery (SSRF) attack through an affected device. 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 sensitive information, or cause the web application to perform arbitrary HTTP requests on behalf of the attacker.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco Identity Services Engine XML External Entity Injection Vulnerability","id":"CVE-2021-34706","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:identity_services_engine","products":["cisco:identity_services_engine"],"type":"xxe","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Evolved Programmable Network Manager Sensitive Information Disclosure Vulnerability","id":"CVE-2021-34707"},"packages":[],"prev":{"headline":"Cisco IOS and IOS XE Software FXO Interface Destination Pattern Bypass Vulnerability","id":"CVE-2021-34705"},"products":["Cisco Identity Services Engine Software"],"published":"2021-10-06","related":[{"cvss_score":10,"headline":"Cisco Identity Services Engine Incorrect Use of Privileged APIs","id":"CVE-2026-76460","kev_date_added":"2026-09-16","published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Injection","id":"CVE-2025-20337","kev_date_added":"2025-07-28","published":"2025-07-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Injection","id":"CVE-2025-20281","kev_date_added":"2025-07-28","published":"2025-06-25"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Hardening Release - Improper Neutralization Vulnerabilities","id":"CVE-2026-20130","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco Identity Services Engine Hardening Release - Access Control Vulnerabilities","id":"CVE-2026-20192","kev_date_added":null,"published":"2026-09-16"},{"cvss_score":10,"headline":"Cisco ISE API Unauthenticated Remote Code Execution Vulnerability","id":"CVE-2025-20282","kev_date_added":null,"published":"2025-06-25"},{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2011-3290","kev_date_added":null,"published":"2011-09-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-07","vendors":["Cisco"]},"summary":"Authenticated attackers can exploit XXE in Cisco ISE to read local files or perform SSRF, leading to information disclosure.","url":"https://insights.sbomify.com/CVE-2021-34706/"}
