By submitting a negative integer for the rotation interval, the backend enters an infinite loop or an invalid state, rendering the web interface unresponsive.\n\n### Details\nThe vulnerability exists in the handler for the POST /api/settings endpoint. Specifically, the logrotate.interval field is accepted as a signed integer without lower-bound verification. When a negative value is processed by the backend logic responsible for scheduling or calculating the next rotation, it triggers a non-terminating loop. This consumes CPU resources and prevents the Go web server from handling further concurrent requests.\n\n**Environment:**\n- OS: Kali Linux 6.17.10-1kali1 (6.17.10+kali-amd64)\n- nginx-ui version: 2.3.3 (513) e5da6dd (go1.26.0 linux/amd64)\n- Deployment: Docker container\n- Run Command: \n```\ndocker run -dit \\\n  --name=nginx-ui \\\n  --restart=always \\\n  -v /mnt/user4/appdata/nginx:/etc/nginx \\\n  -v /mnt/user4/appdata/nginx-ui:/etc/nginx-ui \\\n  -v /var/run/docker.sock:/var/run/docker.sock \\\n  -p 8080:80 -p 8443:443 \\\n  uozi/nginx-ui:latest\n```\n\n### PoC\n1. Authenticate to the nginx-ui dashboard.\n2. Send a POST request to /api/settings (using Burp Suite, Postman, or curl).\n3. Set the payload as follows:\n```\n.\n.\n.\n{\n  \"logrotate\": {\n    \"enabled\": true,\n    \"cmd\": \"logrotate /etc/logrotate.d/nginx\",\n    \"interval\": -1\n  }\n}\n.\n.\n.\n```\n4. Observe that the web server stops responding to all subsequent requests immediately after the injection.\n<img width=\"1041\" height=\"390\" alt=\"image\" src=\"https://github.com/user-attachments/assets/b746a91a-dd63-4f5e-b1a8-382b9d08e181\" />\n\n### Impact\nThis is a High-availability vulnerability (CWE-20: Improper Input Validation). Any authenticated user with access to settings can permanently hang the service.\n\nA patched version of nginx-ui  is available at https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4.","state":0,"publishedAt":"2026-03-30T16:38:38+00:00","modifiedAt":"2026-09-10T03:50:38.6542076+00:00","affected":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","ranges":[{"type":"ECOSYSTEM","events":[{"kind":"introduced","version":"0"},{"kind":"last_affected","version":"1.99"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-cp8r-8jvw-v3qg","https://nvd.nist.gov/vuln/detail/CVE-2026-33029","https://github.com/0xJacky/nginx-ui","https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4"],"sourceUrl":"https://github.com/advisories/GHSA-cp8r-8jvw-v3qg","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-cp8r-8jvw-v3qg","identifiers":["GHSA-cp8r-8jvw-v3qg","CVE-2026-33029","GO-2026-4902"]},"retained":false,"historicalAffected":[]},{"revision":"7d16fb550dda4513a5c4de8eecb600c0","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-4902","aliases":["CVE-2026-33029","GHSA-cp8r-8jvw-v3qg"],"title":"nginx-ui Vulnerable to DoS via Negative Integer Input in Logrotate Interval in github.com/0xJacky/Nginx-UI","description":"nginx-ui Vulnerable to DoS via Negative Integer Input in Logrotate Interval in github.com/0xJacky/Nginx-UI","state":0,"publishedAt":"2026-04-02T18:42:30+00:00","modifiedAt":"2026-04-02T21:19:58.043474+00:00","affected":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-cp8r-8jvw-v3qg","https://nvd.nist.gov/vuln/detail/CVE-2026-33029","https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-4902","license":"OSV · upstream source license applies","key":"osv:GO-2026-4902","identifiers":["GO-2026-4902","CVE-2026-33029","GHSA-cp8r-8jvw-v3qg"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
