An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-33141 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Yarp.ReverseProxy (NuGet): affected all versions; fixed in 1.1.2\n- Yarp.ReverseProxy (NuGet): affected all versions; fixed in 1.1.2\n- Yarp.ReverseProxy (NuGet): affected from 2.0.0; fixed in 2.0.1\n- Yarp.ReverseProxy (NuGet): affected from 2.0.0; fixed in 2.0.1\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-2023-33141/ (Markdown: https://insights.sbomify.com/CVE-2023-33141/index.md)","id":"CVE-2023-33141","markdown":"https://insights.sbomify.com/CVE-2023-33141/index.md","name":"CVE-2023-33141","record":{"aliases":["GHSA-jrjw-qgr2-wfcg"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"YARP reverse proxy","requires_auth":"none","summary":"Attackers can cause a denial of service in the YARP reverse proxy library, affecting applications using this Microsoft NuGet package.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"yet_another_reverse_proxy","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Yet Another Reverse Proxy (YARP) Denial of Service Vulnerability","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Yet Another Reverse Proxy (YARP) Denial of Service Vulnerability","id":"CVE-2023-33141","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":4,"n_references":1,"next":{"headline":"Microsoft SharePoint Server Elevation of Privilege Vulnerability","id":"CVE-2023-33142"},"packages":[{"ecosystem":"NuGet","fixed":["1.1.2"],"introduced":["0"],"last_affected":[],"package":"Yarp.ReverseProxy","purl":null,"source":"GHSA-jrjw-qgr2-wfcg"},{"ecosystem":"NuGet","fixed":["1.1.2"],"introduced":["0"],"last_affected":[],"package":"Yarp.ReverseProxy","purl":"pkg:nuget/Yarp.ReverseProxy","source":"GHSA-jrjw-qgr2-wfcg"},{"ecosystem":"NuGet","fixed":["2.0.1"],"introduced":["2.0.0"],"last_affected":[],"package":"Yarp.ReverseProxy","purl":null,"source":"GHSA-jrjw-qgr2-wfcg"},{"ecosystem":"NuGet","fixed":["2.0.1"],"introduced":["2.0.0"],"last_affected":[],"package":"Yarp.ReverseProxy","purl":"pkg:nuget/Yarp.ReverseProxy","source":"GHSA-jrjw-qgr2-wfcg"}],"prev":{"headline":"Microsoft OneNote Spoofing Vulnerability","id":"CVE-2023-33140"},"products":["YARP 1.0","YARP 2.0"],"published":"2023-06-23","related":[{"cvss_score":7.5,"headline":"YARP Denial of Service Vulnerability","id":"CVE-2022-26924","kev_date_added":null,"published":"2022-04-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-01","vendors":["Microsoft"]},"summary":"Attackers can cause a denial of service in the YARP reverse proxy library, affecting applications using this Microsoft NuGet package.","url":"https://insights.sbomify.com/CVE-2023-33141/"}
