An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-1257 in the wild and no public exploit code.\n\nAffected product: Cisco Digital Network Architecture Center (DNA Center). 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-2021-1257/ (Markdown: https://insights.sbomify.com/CVE-2021-1257/index.md)","id":"CVE-2021-1257","markdown":"https://insights.sbomify.com/CVE-2021-1257/index.md","name":"CVE-2021-1257","record":{"aliases":["GHSA-p8f4-vrqv-6cp2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco DNA Center","requires_auth":"none","summary":"An attacker can trick authenticated users into executing malicious actions on Cisco DNA Center, allowing configuration changes and command execution.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"catalyst_center","vendor":"cisco"},{"product":"agent","vendor":"mcafee"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A vulnerability in the web-based management interface of Cisco DNA Center Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack to manipulate an authenticated user into executing malicious actions without their awareness or consent. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a web-based management user to follow a specially crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the device with the privileges of the authenticated user. These actions include modifying the device configuration, disconnecting the user's session, and executing Command Runner commands.","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 DNA Center Cross-Site Request Forgery Vulnerability","id":"CVE-2021-1257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco AnyConnect Secure Mobility Client Arbitrary File Read Vulnerability","id":"CVE-2021-1258"},"packages":[],"prev":{"headline":"Cisco Firepower Threat Defense Software Command File Overwrite Vulnerability","id":"CVE-2021-1256"},"products":["Cisco Digital Network Architecture Center (DNA Center)"],"published":"2021-01-20","related":[{"cvss_score":9.6,"headline":"Cisco DNA Center Command Runner Command Injection Vulnerability","id":"CVE-2021-1264","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":8,"headline":"Cisco DNA Center Privilege Escalation Vulnerability","id":"CVE-2023-20055","kev_date_added":null,"published":"2023-03-23"},{"cvss_score":7.7,"headline":"Cisco DNA Center Information Disclosure Vulnerability","id":"CVE-2021-1265","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":7.5,"headline":"Cisco Catalyst Center Arbitrary File Read Vulnerability","id":"CVE-2026-20191","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":7.5,"headline":"Cisco Catalyst Center Static SSH Host Key Vulnerability","id":"CVE-2024-20350","kev_date_added":null,"published":"2024-09-25"},{"cvss_score":7.5,"headline":"Cisco DNA Center Information Disclosure Vulnerability","id":"CVE-2020-3411","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":7.4,"headline":"Cisco DNA Center Certificate Validation Vulnerability","id":"CVE-2021-1134","kev_date_added":null,"published":"2021-06-29"}],"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":"2024-11-12","vendors":["Cisco"]},"summary":"An attacker can trick authenticated users into executing malicious actions on Cisco DNA Center, allowing configuration changes and command execution.","url":"https://insights.sbomify.com/CVE-2021-1257/"}
