SCA: security update for pycti (GHSA-4mvw-j8r9-xcgc)

high Tenable Self-Hosted Container Security Plugin ID 443750

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenCTI is an open source platform allowing organizations to manage their cyber threat intelligence
 knowledge and observables. Prior to version 6.1.9, 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. GraphQL Queries in OpenCTI can be validated using the `secureIntrospectionPlugin`. The regex
 check in the plkugin can be bypassed by removing the carriage return and line feed characters (`\r\n`).
 Running a curl command against a local instance of OpenCTI will result in a limited error message. By
 running the same Introspection query without the `\r\n` characters, the unauthenticated user is able to
 successfully run a full Introspection query. 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. Users should upgrade to version 6.1.9 to receive a patch for the issue.
 (CVE-2024-37155)

Solution

Update the pycti library and its related packages to version 6.1.9 or later.
