{"id":"CVE-2026-45564","summary":"Roxy-WI: Authenticated RCE via 'configver' URL parameter (os.system sink in /config/versions/.../save)","details":"Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, POST /config/versions/\u003cservice\u003e/\u003cserver_ip\u003e/\u003cconfigver\u003e/save interpolates the URL-path configver parameter directly into a config-version path that ends up at os.system(f\"dos2unix -q {cfg}\"). configver is not run through EscapedString (Pydantic doesn't validate path segments declared as str) and the surrounding .. block is the broken tuple-membership patch from GHSA-vapt-004. An authenticated user with role \u003c= 3 (\"user\") therefore reaches a bin/sh -c command-injection sink. At time of publication, there are no publicly available patches.","aliases":["GHSA-w42x-3v8j-cmg2"],"modified":"2026-07-08T07:34:23.106342538Z","published":"2026-06-10T14:04:05.080Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45564.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45564.json"},{"type":"ADVISORY","url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-w42x-3v8j-cmg2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45564"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roxy-wi/roxy-wi","events":[{"introduced":"0"},{"last_affected":"d72ea494d0bf1ee220fe141625a4298600f624ad"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"8.2.6.4"}]}}],"versions":["v8.2.6.4","v8.2.6.3","v8.2.8.2","v8.2.8.1","v8.2.6","v8.2.5","v8.2.4","v8.2.3","v8.2.2","v8.2.1","v8.2.0","v8.1.8","v8.1.7","v8.1.6","v8.1.5","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1.0.1","v8.1","v8.0.2","v8.0.1","v8.0","v7.3.2.0","v7.3.1.0","v7.3.0.0","v7.2.6.0","v7.2.5.0","v7.2.4.0","v7.2.3.0","v7.2.2.0","v7.2.1.0","v7.2.0.0","v7.1.2.0","v7.1.1.0","v7.1.0.0","v7.0.4.0","v7.0.3.0","v7.0.2.0","v7.0.1.0","v7.0.0.0","v6.3.19.0","v6.3.18.0","v6.3.17.0","v6.3.16.0","v6.3.15.0","v6.3.14.0","v6.3.13.0","v6.3.12.0","v6.3.11.0","v6.3.10.0","v6.3.9.0","v6.3.8.0","v6.3.7.0","v6.3.6.0","v6.3.5.0","v6.3.4.0","v6.3.3.0","v6.3.2.0","v6.3.1.0","v6.3.0.0","v6.2.3.0","v6.2.2.0","v6.2.1.0","v6.2.0.0","v6.1.5.0","v6.1.4.0","v6.1.3.0","v6.1.2.0","v6.1.1.0","v6.1.0.0","v6.0.3.0","v6.0.2.0","v6.0.1.0","v6.0.0.0","v5.5.1.0","v5.5.0.0","v5.4.3.0","v5.4.2.0","v5.4.1.0","v5.4.0.0","v5.3.6.0","v.5.3.5.0","v5.3.4.0","v5.3.3.0","v5.3.2.0","v5.3.1.0","v5.3.0.0","v5.2.6.0","v5.2.5.0","v5.2.4.0","v5.2.3.0","v5.2.2.0","v5.2.1","v5.2.0","v5.1.4.0","v5.1.1.0","v4.4.1.0","3.4.5.1","3.4.5","3.4.4.7","3.4.4.6","v3.3","v3.2.13","v2.0.2","v1.10.2.1","v1.10.2","v1.10.1","v1.10","v1.9.1","v1.6","v1.4.1","v1.4","v1.3","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45564.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
