Background

Atomix is a distributed systems framework that provides a set of high-level primitives for building fault-tolerant and scalable applications. It allows developers to create distributed variable primitives that can be shared across multiple nodes in a network. These primitives are used by ONOS nodes to share important states. Atomix version 3.1.5 is affected by a vulnerability that allows attackers to access sensitive information when a malicious Atomix node queries distributed variable primitives containing the entire primitive lists used by ONOS nodes.

Vulnerability Detail

The vulnerability arises from a flaw in Atomix v3.1.5, where a malicious Atomix node can exploit the distributed variable primitives to gain unauthorized access to sensitive information. By querying these primitives, an attacker can retrieve important states shared by ONOS nodes, potentially exposing confidential data. The impact of this vulnerability can be significant, as it compromises the integrity and confidentiality of the distributed system. The vulnerability is assigned CVE-2020-35215 and has a CVSS score of 6.5.

Workaround

There is no specific workaround provided for this vulnerability. It is recommended to follow the steps mentioned in the 'how_to_fix' section to upgrade to a patched version of Atomix.

Conclusion

The vulnerability in Atomix v3.1.5 allows malicious Atomix nodes to access sensitive information by querying distributed variable primitives. This can lead to unauthorized access to important states shared by ONOS nodes. To mitigate the risk, it is crucial to upgrade to a patched version of Atomix beyond 3.1.5. Regularly monitoring for security updates and promptly applying them is essential for maintaining the security of the application.
