It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2017-8759 and fix it if it is affected.\n\nWhat it is: CVE-2017-8759 is a high-severity code injection vulnerability in Microsoft .Net Framework, published on 13 Sep 2017. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2017-8759 in the wild since at least 3 Nov 2021.\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-2017-8759/ (Markdown: https://insights.sbomify.com/CVE-2017-8759/index.md)","id":"CVE-2017-8759","markdown":"https://insights.sbomify.com/CVE-2017-8759/index.md","name":"CVE-2017-8759","record":{"aliases":["GHSA-rc4w-p9f6-7c7q"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":".NET Framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via malicious documents or applications exploiting a code injection flaw in the .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":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Microsoft .NET Framework 2.0, 3.5, 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2 and 4.7 allow an attacker to execute code remotely via a malicious document or application, aka \".NET Framework Remote Code Execution Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2017-09-13","github_poc":16,"max_poc_stars":312,"metasploit":0,"nuclei":0,"refs":[{"date":"2017-09-14T10:04:39Z","kind":"github_poc","ref":"https://github.com/bhdresh/CVE-2017-8759","stars":312,"title":"Exploit toolkit CVE-2017-8759 - v1.0 is a handy python script which provides pentesters and security researchers a quick and effective way to test Microsoft .NET Framework RCE.
