Summary

ASPECT is an award-winning scalable building energy management and control solution designed to allow users seamless access to their building data through standard building protocols including smart devices.

Description

Multiple PHP and Java components across the system fail to properly sanitize user-supplied input before including it in application logs. In PHP, files like supervisorProxy.php directly embed values such as $_SERVER['REQUEST_URI'] and raw POST bodies into log messages without filtering, enabling attackers to inject arbitrary log entries using encoded newline characters. Similarly, Java classes using LoggerUtil.logger.* methods concatenate user-controlled strings like usernames and cookie keys into logs without validation. This systemic flaw allows for log forging, manipulating log content to obfuscate activity, insert misleading entries, or facilitate follow-up attacks.
