Prior to 3.8.6, the pre-installation web/instalador/instalador.php endpoint is reachable before config.php exists and processes unauthenticated installation POST data. In the Linux reinstall flow, a crafted usuario value reaches a command executed by shell_exec(). The installer also writes attacker-controlled values into executable config.php and concatenates the database name nomebd into a CREATE DATABASE statement. Successful exploitation can execute commands as the web-server user, persist attacker-controlled PHP configuration, and alter or disrupt the application and its data. This issue is fixed in version 3.8.6.","categories":["Unclassified"],"product":"WeGIA","vendor":"LabRedesCefetRJ","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55679","source_modified_at":"2026-10-20T02:06:11.939Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"WeGIA","vendor":"LabRedesCefetRJ","versions":[{"version":"< 3.8.6","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00428,"percentile":0.36061,"score_date":"2026-10-23"},"published_at":"2026-10-14T19:44:02.494Z","modified_at":"2026-10-20T02:06:11.939Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55679","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:06:11.939Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55679","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-wm6j-4rfm-399q","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/LabRedesCefetRJ/WeGIA/issues/96","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LabRedesCefetRJ/WeGIA/pull/1705","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LabRedesCefetRJ/WeGIA/commit/b13c4b0b416d99a8145f583e0893bc8172155469","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LabRedesCefetRJ/WeGIA/releases/tag/3.8.6","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-20T02:05:51.738763Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:06:11.939Z","content_hash":"3fb032ab5749323c37e536ecb6ecd24b9192e45e5bd517238e17db7329fabe3f"}}
