AI-suggested
1. Immediately restrict network access to the management web interface of affected Circutor devices, ideally isolating them on dedicated management VLANs or networks with strict firewall rules. 2. Implement strong authentication and access control measures to limit who can apply configuration changes. 3. Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block malicious payloads targeting the 'index.cgi' endpoint. 4. Monitor device logs and network traffic for unusual configuration changes or command execution attempts. 5. Coordinate with Circutor for firmware updates or patches addressing CVE-2025-11779 and apply them promptly once available. 6. If patches are not yet available, consider temporary mitigations such as disabling remote configuration capabilities or limiting configuration changes to trusted administrators via secure channels. 7. Conduct regular security assessments and penetration tests on industrial control systems to identify and remediate similar vulnerabilities proactively.
Description
Stack-based buffer overflow vulnerability in CircutorSGE-PLC1000/SGE-PLC50 v9.0.2. The 'SetLan' function is invoked when a new configuration is applied. This new configuration function is activated by a management web request, which can be invoked by a user when making changes to the 'index.cgi' web application. The parameters are not being sanitised, which could lead to command injection.
