An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-21554 and fix it if it is affected.\n\nWhat it is: CVE-2023-21554 is a critical code injection vulnerability in Microsoft Windows 10 1607, published on 11 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-21554 exists.\n\nAffected product: Microsoft Windows 10 1607. 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-2023-21554/ (Markdown: https://insights.sbomify.com/CVE-2023-21554/index.md)","id":"CVE-2023-21554","markdown":"https://insights.sbomify.com/CVE-2023-21554/index.md","name":"CVE-2023-21554","record":{"aliases":["GHSA-xvhr-xr27-hpmq"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows MSMQ","requires_auth":"none","summary":"Attackers can execute arbitrary code remotely via Microsoft Message Queuing, requiring immediate patching on affected Windows systems.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_10_20h2","vendor":"microsoft"},{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_21h2","vendor":"microsoft"},{"product":"windows_11_22h2","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Microsoft Message Queuing (MSMQ) Remote Code Execution Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-04-11","github_poc":6,"max_poc_stars":60,"metasploit":1,"nuclei":0,"refs":[{"date":"2023-05-18T10:30:49Z","kind":"github_poc","ref":"https://github.com/zoemurmure/CVE-2023-21554-PoC","stars":60,"title":"CVE-2023-21554 Windows MessageQueuing PoC，分析见 https://www.zoemurmure.top/posts/cve_2023_21554/"},{"date":"2023-08-17T17:16:46Z","kind":"github_poc","ref":"https://github.com/3tternp/CVE-2023-21554","stars":28,"title":null},{"date":"2025-03-31T09:06:57Z","kind":"github_poc","ref":"https://github.com/leongxudong/MSMQ-Vulnerability","stars":5,"title":"Documentation and PoC for CVE-2023-21554 MSMQ Vulnerability"},{"date":"2025-10-09T19:02:16Z","kind":"github_poc","ref":"https://github.com/shootweb/CVE-2023-21554","stars":2,"title":"CVE-2023-21554 PoC"},{"date":"2023-04-11","kind":"metasploit","ref":"auxiliary/scanner/msmq/cve_2023_21554_queuejumper","stars":null,"title":"CVE-2023-21554 -
