Description

EyesOfNetwork contains a vulnerability due to the use of hard-coded credentials, specifically the same default API key. This flaw allows attackers to calculate or guess the admin access token, potentially leading to unauthorized administrative access. The vulnerability has been exploited in the wild.

Summary

CVE-2020-8657 identifies a security weakness in EyesOfNetwork where a hard-coded API key is used by default. This design flaw enables attackers to derive or guess the administrative access token, compromising the system's security controls. The vulnerability is classified under CWE-798 (Use of Hard-coded Credentials) and has been observed in active exploitation scenarios.

Impact

Exploitation of this vulnerability allows attackers to gain administrative access to EyesOfNetwork by leveraging the default hard-coded API key. This can lead to unauthorized control over the system, potentially compromising monitoring and management functions.

Mitigation

No specific patch or official fix information is provided. Since EyesOfNetwork is not a cloud service, users should consult the vendor's advisory for remediation guidance. Until a patch is available, it is recommended to change default credentials and API keys if possible and restrict access to the affected interfaces.
