An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2018-8260 and fix it if it is affected.\n\nWhat it is: CVE-2018-8260 is a high-severity code injection vulnerability in Microsoft .Net Framework, published on 11 Jul 2018. 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-2018-8260 in the wild and no public exploit code.\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-2018-8260/ (Markdown: https://insights.sbomify.com/CVE-2018-8260/index.md)","id":"CVE-2018-8260","markdown":"https://insights.sbomify.com/CVE-2018-8260/index.md","name":"CVE-2018-8260","record":{"aliases":["GHSA-q76h-pfpm-pgpp"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":".NET Framework","requires_auth":"none","summary":"Attackers can execute arbitrary code by exploiting a failure to validate source markup in .NET Framework files.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":".net_framework","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A Remote Code Execution vulnerability exists in .NET software when the software fails to check the source markup of a file, aka \".NET Framework Remote Code Execution Vulnerability.\" This affects .NET Framework 4.7.2, Microsoft .NET Framework 4.7.2.","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":"Code injection in .NET Framework","id":"CVE-2018-8260","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:.net_framework","products":["microsoft:.net_framework"],"type":"code_injection","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2018-8261"},"packages":[],"prev":{"headline":"Code injection in Microsoft.PowerShell.Archive","id":"CVE-2018-8256"},"products":[".NET Framework","Microsoft .NET Framework"],"published":"2018-07-11","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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code by exploiting a failure to validate source markup in .NET Framework files.","url":"https://insights.sbomify.com/CVE-2018-8260/"}
