CVE-2019-10243 in Kura
Summary
by MITRE
In Eclipse Kura versions up to 4.0.0, Kura exposes the underlying Ui Web server version in its replies. This can be used as a hint by an attacker to specifically craft attacks to the web server run by Kura.

The vulnerability identified as CVE-2019-10243 affects Eclipse Kura versions up to 4.0.0, where the platform inadvertently reveals the underlying web server version information through its responses. This exposure occurs within the user interface web server component that Kura employs to deliver its web-based management interface. The disclosure of version information creates a significant security risk as it provides attackers with specific knowledge about the software stack being utilized, enabling them to target known vulnerabilities associated with particular versions of the underlying web server.
This vulnerability represents a classic information disclosure issue that aligns with CWE-200, which categorizes the improper exposure of sensitive information. The flaw operates at the application layer where the web server responses contain version headers or other identifying metadata that should be stripped or obfuscated to prevent attackers from gaining insights into the system's technical implementation. The exposed version information serves as a critical piece of reconnaissance data that attackers can leverage to build targeted exploitation strategies.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables more sophisticated attack vectors that can be mapped to the MITRE ATT&CK framework under the technique T1068, which involves the use of remote services and system information gathering. Attackers can utilize the disclosed version information to identify specific vulnerabilities in the underlying web server software, potentially leading to privilege escalation, data compromise, or system takeover scenarios. The exposure creates an attack surface that reduces the overall security posture of Kura deployments, particularly in environments where the platform serves as a management interface for critical infrastructure components.
Mitigation strategies for this vulnerability should focus on implementing proper header sanitization and response obfuscation within the Kura web server configuration. Organizations should ensure that version information is stripped from HTTP response headers and that the web server operates with minimal information disclosure. The recommended approach involves configuring the underlying web server to suppress version strings in server headers, implementing proper security headers, and conducting regular security audits to verify that no sensitive information is exposed through application responses. Additionally, network segmentation and access controls should be implemented to limit exposure of the Kura management interface to authorized personnel only, thereby reducing the potential impact of information disclosure vulnerabilities.
