Ruijie NBR1300G Exposure Scanner

Ruijie NBR1300G is a network router often employed by organizations to facilitate secure and stable internet connectivity. It's widely used in corporate offices, educational institutions, and other environments where reliable network infrastructure is essential. Administrators utilize Ruijie NBR1300G to manage network traffic, implement security policies, and ensure efficient data communication. The router is valued for its capability to support multiple users and its ease of integration into existing network setups. Ensuring its configuration adheres to best practices is vital to maintaining the integrity and security of the network it manages. Network administrators are encouraged to keep software updated to mitigate vulnerabilities.

The Ruijie NBR1300G Exposure vulnerability involves unauthorized access to sensitive CLI (Command Line Interface) passwords due to misconfiguration. This exposure poses a significant risk by potentially allowing unauthorized users to execute CLI commands. Attackers exploiting this vulnerability can gain privileged access, compromising the router's configuration and potentially the entire network. The detection of such vulnerabilities is crucial for maintaining security posture and protecting sensitive data. Regular vulnerability assessments and timely patching are essential to prevent unauthorized access. Recognizing and addressing this exposure will help secure network infrastructure against potential breaches.

The Ruijie NBR1300G vulnerability is specifically related to the CLI password leak due to inadequate access control in configuration settings. The endpoint involves executing a POST request to "/WEB_VMS/LEVEL15/" with specific authorization data, leading to exposure if mismanaged. Observing the response body for indications like "webmaster level 2 username guest password guest" confirms the presence of the vulnerability. The issue results from a failure to properly restrict access to sensitive configuration areas, allowing default or weak credentials to result in unauthorized access. Proper authentication mechanisms must be in place to mitigate such vulnerabilities.

Exploitation of the Ruijie NBR1300G Exposure vulnerability can have several detrimental effects. Unauthorized access can lead to changes in network configurations, potentially causing network downtimes or disruptions. Sensitive data may be intercepted or altered, leading to data breaches or loss of confidentiality. Integrity of the network can be compromised, enabling further attacks or exploitation by malicious entities. There is a risk of persistent unauthorized access, allowing attackers to maintain control over the network device. Lastly, this vulnerability may be used as a stepping stone for broader network attacks, increasing the risk to connected systems.
