Executive Summary

This vulnerability is a Cleartext Transmission of Sensitive Information issue in Apache APISIX. It occurs because the 'ssl_verify' setting in the openid-connect plugin configuration is set to false by default, which means that sensitive information may be transmitted without proper encryption or verification.

The vulnerability affects Apache APISIX versions from 0.7 through 3.15.0.

Mitigation Strategies

To mitigate the Cleartext Transmission of Sensitive Information vulnerability in Apache APISIX, users are recommended to upgrade Apache APISIX to version 3.16.0, which fixes the issue.

This vulnerability occurs because the 'ssl_verify' setting in the openid-connect plugin configuration is set to false by default. Ensuring this setting is properly configured or upgrading to the fixed version will help mitigate the risk.

Useful 0 Not Useful 0

Compliance Impact

The vulnerability involves cleartext transmission of sensitive information due to the openid-connect plugin's ssl_verify setting being false by default. This can lead to interception of sensitive data.

Such exposure of sensitive information could potentially impact compliance with standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data during transmission.

However, the provided information does not explicitly discuss the direct impact on compliance with these standards.

Detection Guidance

This vulnerability occurs because the `ssl_verify` field in the openid-connect plugin configuration of Apache APISIX is set to false by default, leading to cleartext transmission of sensitive information.

To detect this vulnerability on your system, you should check the configuration of the openid-connect plugin in your Apache APISIX installation to see if `ssl_verify` is set to false.

Additionally, you can monitor network traffic for unencrypted transmission of sensitive data related to openid-connect plugin operations.

• Check the plugin configuration file or API for the `ssl_verify` setting, for example by using commands like `grep -r ssl_verify /path/to/apisix/conf/`.
• Use network packet capture tools such as `tcpdump` or `wireshark` to inspect traffic on relevant ports for unencrypted sensitive information.
• Example command to check configuration: `grep -r ssl_verify /usr/local/apisix/conf/`
• Example command to capture traffic: `tcpdump -i eth0 port 443 -w capture.pcap` and then analyze with Wireshark for any cleartext sensitive data.
