In Apache APISIX Dashboard version 2.6, we changed the default value of listen host to 0.0.0.0 in order to facilitate users to configure external network access. In the IP allowed list restriction, a risky function was used for the IP acquisition, which made it possible to bypass the network limit. At the same time, the default account and password are fixed.Ultimately these factors lead to the issue of security risks. This issue is fixed in APISIX Dashboard 2.6.1

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Apisix_dashboard Apache 2.6 (including) 2.6 (including)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
