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-2013-2028 exists.\n\nAffected product: Fedoraproject Fedora. 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-2013-2028/ (Markdown: https://insights.sbomify.com/CVE-2013-2028/index.md)","id":"CVE-2013-2028","markdown":"https://insights.sbomify.com/CVE-2013-2028/index.md","name":"CVE-2013-2028","record":{"aliases":["GHSA-68mc-8233-5xrw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Web server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause a denial of service via a crafted chunked Transfer-Encoding request in nginx.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"nginx","vendor":"f5"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The ngx_http_parse_chunked function in http/ngx_http_parse.c in nginx 1.3.9 through 1.4.0 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a chunked Transfer-Encoding request with a large chunk size, which triggers an integer signedness error and a stack-based buffer overflow.","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2013-05-07","github_poc":8,"max_poc_stars":54,"metasploit":1,"nuclei":0,"refs":[{"date":"2016-03-23T10:41:00Z","kind":"github_poc","ref":"https://github.com/kitctf/nginxpwn","stars":54,"title":"Exploitation Training -- CVE-2013-2028: Nginx Stack Based Buffer Overflow"},{"date":"2013-05-21T15:20:05Z","kind":"github_poc","ref":"https://github.com/danghvu/nginx-1.4.0","stars":30,"title":"For the analysis of CVE-2013-2028"},{"date":"2020-06-27T15:08:26Z","kind":"github_poc","ref":"https://github.com/m4drat/CVE-2013-2028-Exploit","stars":19,"title":"CVE-2013-2028 python exploit"},{"date":"2019-08-03T07:38:18Z","kind":"github_poc","ref":"https://github.com/tachibana51/CVE-2013-2028-x64-bypass-ssp-and-pie-PoC","stars":2,"title":"this is not stable"},{"date":"2021-07-08T17:17:34Z","kind":"github_poc","ref":"https://github.com/jptr218/nginxhack","stars":1,"title":"A CVE-2013-2028 implementation"},{"date":"2013-05-07","kind":"metasploit","ref":"exploit/linux/http/nginx_chunked_size","stars":null,"title":"Nginx HTTP Server 1.3.9-1.4.0 Chunked Encoding Stack Buffer Overflow"},{"date":"2013-05-17","kind":"exploitdb","ref":"25499","stars":null,"title":"Nginx 1.3.9 \u003c 1.4.0 -
