CVE-2026-55679 · Severity: medium · CVSS 6.5 · Published 2026-10-14

WeGIA is a web manager for charitable institutions that remains accessible during initial setup before proper configuration is completed. An attacker can reach the unprotected installer endpoint and submit malicious data that gets executed as shell commands with web-server privileges or written into the application's configuration file, allowing unauthorized code execution, data loss, or application disruption.

Technical details

The pre-installation endpoint web/instalador/instalador.php is reachable before config.php exists and accepts unauthenticated POST data without validation. In the Linux reinstall flow, a crafted usuario parameter reaches shell_exec(), enabling remote command execution. Additionally, attacker-controlled values are written into executable config.php and the unvalidated database name (nomebd) is concatenated into SQL CREATE DATABASE statements without escaping, enabling code injection and SQL injection. The vulnerability requires network access and no authentication.
