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-2025-55315/ (Markdown: https://insights.sbomify.com/CVE-2025-55315/index.md)","id":"CVE-2025-55315","markdown":"https://insights.sbomify.com/CVE-2025-55315/index.md","name":"CVE-2025-55315","record":{"aliases":["BELL-CVE-2025-55315","BIT-aspnet-core-2025-55315","GHSA-5rrx-jjjq-q2r5","UBUNTU-CVE-2025-55315"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ASP.NET Core framework","requires_auth":"low_privilege","summary":"An authorized attacker can bypass security features via HTTP request smuggling in ASP.NET Core, requiring a patch.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"asp.net_core","vendor":"microsoft"},{"product":"visual_studio_2022","vendor":"microsoft"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an authorized attacker to bypass a security feature over a network.","ecosystems":["Bitnami","NuGet"],"exploits":{"exploitdb":1,"first_seen":"2025-10-16","github_poc":7,"max_poc_stars":46,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-10-16T17:14:56Z","kind":"github_poc","ref":"https://github.com/sirredbeard/CVE-2025-55315-repro","stars":46,"title":"Tool that reproduces CVE-2025-55315 in ASP.NET Core."},{"date":"2025-11-11T07:22:16Z","kind":"github_poc","ref":"https://github.com/ZemarKhos/CVE-2025-55315-PoC-Exploit","stars":10,"title":"CVE-2025-55315 PoC Exploit"},{"date":"2025-10-16T15:31:27Z","kind":"github_poc","ref":"https://github.com/nickcopi/CVE-2025-55315-detection-playground","stars":7,"title":"Playground to experiment with different behavior on patched/unpatched Kestrel for the CVE-2025-55315 HTTP smuggling vulnerability"},{"date":"2025-10-19T02:02:46Z","kind":"github_poc","ref":"https://github.com/7huukdlnkjkjba/CVE-2025-55315-","stars":6,"title":"专业级HTTP请求走私漏洞利用与自动化渗透测试工具"},{"date":"2025-10-24T14:19:43Z","kind":"github_poc","ref":"https://github.com/jlinebau/CVE-2025-55315-Scanner-Monitor","stars":2,"title":"Quick and Simple Scripts to Scan for Vulnerable Servers and Packet Level Monitors"},{"date":"2025-11-27T09:09:28Z","kind":"github_poc","ref":"https://github.com/MartinFabianIonut/CVE-2025-55315","stars":1,"title":"Proof-of-concept exploit for CVE-2025-55315 (.NET HTTP Request Smuggling).
