Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1530 in the wild and no public exploit code.\n\nAffected product: Cisco BroadWorks. 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-2021-1530/ (Markdown: https://insights.sbomify.com/CVE-2021-1530/index.md)","id":"CVE-2021-1530","markdown":"https://insights.sbomify.com/CVE-2021-1530/index.md","name":"CVE-2021-1530","record":{"aliases":["GHSA-fv3h-9947-8cpj"],"analysis":{"component_type":"server_software","fix_type":"workaround","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BroadWorks Messaging Server","requires_auth":"low_privilege","summary":"An authenticated attacker can exploit XXE in Cisco BroadWorks Messaging Server to read local files or cause partial denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"broadworks_messaging_server","vendor":"cisco"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","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 BroadWorks Messaging Server Software could allow an authenticated, remote attacker to access sensitive information or cause a partial denial of service (DoS) condition on an affected system. 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 application to consume available resources, resulting in a partial DoS condition on an affected system. There are workarounds that address this vulnerability.","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 BroadWorks Messaging Server XML External Entity Injection Vulnerability","id":"CVE-2021-1530","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Modeling Labs Web UI Command Injection Vulnerability","id":"CVE-2021-1531"},"packages":[],"prev":{"headline":"Cisco IOS XE SD-WAN Software Command Injection Vulnerability","id":"CVE-2021-1529"},"products":["Cisco BroadWorks"],"published":"2021-05-06","related":[{"cvss_score":7.7,"headline":"Server-side request forgery in Cisco BroadWorks","id":"CVE-2022-20951","kev_date_added":null,"published":"2022-11-03"}],"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":"2024-11-08","vendors":["Cisco"]},"summary":"An authenticated attacker can exploit XXE in Cisco BroadWorks Messaging Server to read local files or cause partial denial of service.","url":"https://insights.sbomify.com/CVE-2021-1530/"}
