An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3256 in the wild and no public exploit code.\n\nAffected product: Cisco Hosted Collaboration Mediation Fulfillment. 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-2020-3256/ (Markdown: https://insights.sbomify.com/CVE-2020-3256/index.md)","id":"CVE-2020-3256","markdown":"https://insights.sbomify.com/CVE-2020-3256/index.md","name":"CVE-2020-3256","record":{"aliases":["GHSA-j23c-hpx8-w7p9"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco HCM-F","requires_auth":"high_privilege","summary":"An authenticated admin can exploit an XXE vulnerability in Cisco HCM-F to read sensitive files from the local system.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"hosted_collaboration_mediation_fulfillment","vendor":"cisco"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A vulnerability in the web-based management interface of Cisco Hosted Collaboration Mediation Fulfillment (HCM-F) Software could allow an authenticated, remote attacker to gain read access to information that is stored on an affected system. To exploit this vulnerability, an attacker would need administrative privileges on the Cisco HCM-F Software. The vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by sending malicious requests that contain references in XML entities to an affected system. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of sensitive information.","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 Hosted Collaboration Mediation Fulfillment XML External Expansion Vulnerability","id":"CVE-2020-3256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOx Application Environment for IOS Software for Cisco Industrial Routers Vulnerabilities","id":"CVE-2020-3257"},"packages":[],"prev":{"headline":"Cisco Firepower Threat Defense Software Packet Flood Denial of Service Vulnerability","id":"CVE-2020-3255"},"products":["Cisco Hosted Collaboration Mediation Fulfillment"],"published":"2020-05-06","related":[{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2016-6371","kev_date_added":null,"published":"2016-09-12"},{"cvss_score":6.5,"headline":"Cisco Hosted Collaboration Mediation Fulfillment Cross-Site Request Forgery Vulnerability","id":"CVE-2020-3124","kev_date_added":null,"published":"2020-09-23"},{"cvss_score":6.5,"headline":"Cisco Hosted Collaboration Mediation Fulfillment Cross-Site Request Forgery Vulnerability","id":"CVE-2018-15401","kev_date_added":null,"published":"2018-10-05"},{"cvss_score":6.5,"headline":"Cross-site request forgery in Cisco Hosted Collaboration Mediation Fulfillment before 11.5(0.98000.216)","id":"CVE-2016-6454","kev_date_added":null,"published":"2016-11-03"},{"cvss_score":5.3,"headline":"Cisco Unified Communications Manager Denial of Service Vulnerability","id":"CVE-2021-1478","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":4.3,"headline":"Path traversal in n/a","id":"CVE-2016-6370","kev_date_added":null,"published":"2016-09-12"}],"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":"2024-11-15","vendors":["Cisco"]},"summary":"An authenticated admin can exploit an XXE vulnerability in Cisco HCM-F to read sensitive files from the local system.","url":"https://insights.sbomify.com/CVE-2020-3256/"}
