{"id":"CVE-2026-55679","published":"2026-10-14T20:17:50.030","lastModified":"2026-10-14T20:17:50.160","description":"WeGIA is a web manager for charitable institutions. 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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:L","cwes":["CWE-78","CWE-89","CWE-94"],"vendors":[],"products":[],"references":[{"url":"https://github.com/LabRedesCefetRJ/WeGIA/commit/b13c4b0b416d99a8145f583e0893bc8172155469","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/issues/96","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/pull/1705","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/releases/tag/3.8.6","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-wm6j-4rfm-399q","tags":[]}],"exploitRefs":[{"url":"https://github.com/LabRedesCefetRJ/WeGIA/commit/b13c4b0b416d99a8145f583e0893bc8172155469","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/issues/96","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/pull/1705","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/releases/tag/3.8.6","tags":[]},{"url":"https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-wm6j-4rfm-399q","tags":[]}],"hasPoc":true,"ai":null}
