An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2014-0257 exists.\n\nAffected product: Microsoft .Net Framework. 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-2014-0257/ (Markdown: https://insights.sbomify.com/CVE-2014-0257/index.md)","id":"CVE-2014-0257","markdown":"https://insights.sbomify.com/CVE-2014-0257/index.md","name":"CVE-2014-0257","record":{"aliases":["GHSA-x4qf-4j36-qp5x"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft .NET Framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via crafted websites or COM endpoints due to improper method safety checks in .NET Framework.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net_framework","vendor":"microsoft"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Microsoft .NET Framework 1.0 SP3, 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4, 4.5, and 4.5.1 does not properly determine whether it is safe to execute a method, which allows remote attackers to execute arbitrary code via (1) a crafted web site or (2) a crafted .NET Framework application that exposes a COM server endpoint, aka \"Type Traversal Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2014-02-11","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2014-02-11","kind":"metasploit","ref":"exploit/windows/local/ms14_009_ie_dfsvc","stars":null,"title":"MS14-009 .NET Deployment Service IE Sandbox Escape"},{"date":"2014-06-27","kind":"exploitdb","ref":"33892","stars":null,"title":"Microsoft .NET Deployment Service - IE Sandbox Escape (MS14-009) (Metasploit)"}],"tier":"weaponised"},"has_fix":null,"headline":"Code injection in n/a","id":"CVE-2014-0257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:.net_framework","products":["microsoft:.net_framework"],"type":"code_injection","year":"2014"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2014-0258"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2014-0256"},"products":["n/a"],"published":"2014-02-12","related":[{"cvss_score":9.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2020-0646","kev_date_added":"2021-11-03","published":"2020-01-14"},{"cvss_score":7.8,"headline":"Microsoft .NET Framework Remote Code Execution","id":"CVE-2017-8759","kev_date_added":"2021-11-03","published":"2017-09-13"},{"cvss_score":7.8,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2015-1671","kev_date_added":"2022-05-25","published":"2015-05-13"},{"cvss_score":7.5,"headline":"Microsoft .NET Framework Information Disclosure","id":"CVE-2024-29059","kev_date_added":"2025-02-04","published":"2024-03-22"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2014-4073","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-4121","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2014-1806","kev_date_added":null,"published":"2014-05-14"}],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via crafted websites or COM endpoints due to improper method safety checks in .NET Framework.","url":"https://insights.sbomify.com/CVE-2014-0257/"}
