CVE-2019-7693 in Axios RE
Summary
by MITRE
Axios Italia Axios RE 1.7.0/7.0.0 devices have XSS via the RELogOff.aspx Error_Parameters parameter. In some situations, the XSS would be on the family.axioscloud.it cloud service; however, the vendor also supports "Sissi in Rete (con server)" for offline operation.

The vulnerability CVE-2019-7693 affects Axios Italia Axios RE 1.7.0 and 7.0.0 devices, representing a cross-site scripting flaw that manifests through the RELogOff.aspx Error_Parameters parameter. This security weakness exists within the web interface of these devices, specifically targeting the authentication termination process where users are redirected after logout operations. The vulnerability is particularly concerning because it affects both cloud-based operations and offline deployment scenarios, as the vendor supports both "Sissi in Rete (con server)" configurations and the family.axioscloud.it cloud service infrastructure, creating a dual attack surface that extends beyond traditional network boundaries.
The technical implementation of this XSS vulnerability occurs when the application fails to properly sanitize user input parameters, specifically the Error_Parameters value passed to the RELogOff.aspx page. When a user encounters an error during logout or authentication, the system redirects them to this page while embedding the error parameters directly into the HTML response without adequate output encoding or validation. This allows an attacker to inject malicious script code that executes in the context of other users' browsers who visit the affected page. The vulnerability is classified as CWE-79 - Cross-Site Scripting, which is a fundamental web application security flaw that enables attackers to execute scripts in the victim's browser context.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable attackers to perform session hijacking, steal user credentials, and access sensitive information within the device management interface. Given that these devices are part of the Axios Italia RE series, which includes security cameras and surveillance equipment, the potential for unauthorized access to video feeds and system configurations is significant. The cloud service component adds additional risk as attackers could compromise multiple devices simultaneously if they can manipulate the shared cloud infrastructure. This vulnerability particularly affects the security posture of organizations relying on these devices for surveillance and access control systems, potentially allowing attackers to gain unauthorized access to physical security systems through web-based attack vectors.
Mitigation strategies for CVE-2019-7693 should focus on immediate input validation and output encoding measures to prevent script injection attacks. Organizations should implement proper parameter sanitization on all user-supplied inputs, particularly those used in redirection and error handling scenarios. The vendor should provide a security patch that ensures all error parameters are properly escaped before being rendered in the web interface. Network segmentation and monitoring solutions should be deployed to detect anomalous traffic patterns that might indicate exploitation attempts. Additionally, security awareness training for administrators should emphasize the importance of keeping firmware updated and monitoring for unusual error messages that could indicate XSS exploitation attempts. This vulnerability aligns with ATT&CK technique T1059.007 - Command and Scripting Interpreter: JavaScript, as it enables attackers to execute malicious JavaScript code through the vulnerable web interface. The affected devices should also be configured to use secure HTTP headers including Content Security Policy to prevent execution of unauthorized scripts, and administrators should consider implementing web application firewalls to detect and block malicious payloads targeting this specific vulnerability.
