Critical Aviatrix Security Flaw Enables Hackers to Deploy Backdoors

Critical Security Flaw in Aviatrix Controller Exploited for Backdoor Attacks and Cryptocurrency Mining

A newly uncovered security vulnerability in the Aviatrix Controller cloud networking platform has raised alarms across the cybersecurity community. This critical flaw, identified as CVE-2024-50603, has a maximum severity score of 10.0 and is currently being actively exploited by cybercriminals to install backdoors and deploy cryptocurrency miners. Organizations using Aviatrix Controller are urged to take immediate action to mitigate risks associated with this vulnerability.

Understanding the CVE-2024-50603 Vulnerability

The CVE-2024-50603 vulnerability allows unauthenticated remote code execution, which means that attackers can execute malicious commands on affected systems. The flaw stems from certain API endpoints that fail to properly sanitize user inputs. This oversight can lead to severe consequences, enabling attackers to inject harmful operating system commands. Fortunately, Aviatrix has addressed this issue in versions 7.1.4191 and 7.2.4996.

Recent Incidents and Exploitation

According to cloud security firm Wiz, multiple incidents related to the exploitation of CVE-2024-50603 have been reported. Jakub Korepta, a researcher from the Polish cybersecurity firm Securing, discovered and reported this vulnerability, and a proof-of-concept (PoC) exploit is now publicly available.

  • Key Statistics:
    • Approximately 3% of cloud enterprise environments utilize Aviatrix Controller.
    • Of these, 65% exhibit a lateral movement path to administrative cloud control plane permissions, heightening the risk of privilege escalation.

Risks in AWS Environments

Wiz researchers have highlighted that when deployed in AWS cloud environments, the Aviatrix Controller inherently allows privilege escalation. This makes the exploitation of CVE-2024-50603 particularly dangerous. "The potential impact of this vulnerability is significant, especially in cloud setups," stated Wiz researchers Gal Nagli, Merav Bar, Gili Tikochinski, and Shaked Tanchuma.

Real-world attacks leveraging this flaw have shown that threat actors are gaining initial access to target instances to mine cryptocurrencies using XMRig and deploying the Sliver command-and-control (C2) framework for persistence and further exploitation.

Recommended Actions for Users

Given the active exploitation of CVE-2024-50603, it is crucial for users of the Aviatrix Controller to take immediate action:

  • Apply Security Patches: Update to the latest versions (7.1.4191 and 7.2.4996) to mitigate this vulnerability.
  • Restrict Public Access: Limit public access to the Aviatrix Controller to reduce the risk of unauthorized exploitation.
