Credential Disclosure vulnerabilities pose a significant threat as they can allow unauthorized access to sensitive information such as WiFi passwords. This specific vulnerability allows remote unauthenticated users to retrieve the WiFi password of a device. Exploiting this vulnerability can lead to unauthorized network access, potentially compromising connected devices. Understanding and mitigating such vulnerabilities is essential to maintain network security and protect user privacy. This vulnerability underscores the constant need for vigilance in safeguarding against unauthorized data access and exposure.

The vulnerability in question involves unauthorized access to WiFi credentials through specific HTTP requests. The endpoint exposed to attack is "/netcore_get.cgi," which returns sensitive information when accessed improperly. The vulnerable parameters include identifiers like "rp_ap_password" and "rp_ap_ssid," indicating the disclosure of WiFi-related data. The exposure can be detected by receiving a successful response containing these disclosures, typically in clear text. The template identifies this condition by verifying response status and matching specific body content, thereby confirming the presence of the vulnerability. Consequently, securing this endpoint is critical to prevent unintended information leaks.

When this vulnerability is exploited, attackers can gain unrestricted access to the wireless network, potentially leading to data theft, malware distribution, or service disruption. Unauthorized users might manipulate network settings or monitor communications, endangering both personal and corporate information. Systems connected to the network might become susceptible to further attacks or infections, emphasizing the importance of timely remediation. Additionally, the organization might face financial losses or reputational damage due to breach incidents. Ensuring robust access controls and timely updates can mitigate such potential impacts.
