Summary
OpenCTI May Bypass Introspection Restriction
Details

Summary

The regex validation used to prevent Introspection queries can be bypassed by removing the extra whitespace, carriage return, and line feed characters from the query.

Details

GraphQL Queries in OpenCTI can be validated using the secureIntrospectionPlugin.

Impact

Bypassing this restriction allows the attacker to gather a wealth of information about the GraphQL endpoint functionality that can be used to perform actions and/or read data without authorization. These queries can also be weaponized to conduct a Denial of Service (DoS) attack if sent repeatedly.

Severity
6.5 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L
