3CX Advises Disabling SQL Database Integration

Notification due to a Potential Vulnerability

The VoIP communications company 3CX issued a warning to its customers to disable SQL database integrations after a potential vulnerability was brought to light. This advisory was prompted by the discovery of a SQL injection flaw, which was identified by independent security researcher Theo Stein. The company communicated this concern through a security notice and strongly advised its client base to take immediate action to safeguard their systems.

Impact on 3CX Versions 18 and 20

According to Pierre Jourdan, 3CX's chief information security officer, the security issue in question specifically affects versions 18 and 20 of the 3CX Voice Over Internet Protocol (VoIP) software. Users operating on these versions have been promptly informed to assess and directly address the vulnerabilities related to their SQL database integrations to evade potential attacks and breaches.

Affects a Small Percentage of Users with Legacy Integration

The flaw identified is known to pose a risk mainly to users utilizing legacy SQL database templates which include MsSQL, MySQL, and PostgreSQL. The advice from 3CX CEO Nick Galea points out that the vulnerability could lead to SQL injection attacks particularly when the 3CX servers are exposed to the internet without the protection of a Web application firewall. It was clarified, however, that the risk is confined to these specific SQL integrations and does not extend to all web-based CRM integrations or users utilizing the MongoDB database.

Recommendation for Users of MongoDB, MsSQL, MySQL, and PostgreSQL Databases

For those customers who are using SQL Database integrations based on the aforementioned templates, the recommendation is to disable these integrations as a preventative measure. This precaution is to remain in effect until a fix is developed and released by 3CX. Notably, users who have adopted web-based CRM integration templates or are using MongoDB are not affected by this issue and therefore need not take action.

Steps to Disable the Integration

Customers who need to disable their SQL database integrations can follow the guidelines provided by 3CX to mitigate the risk. Although details of the exact steps were not explicitly provided in the public advisories, affected users are directed to consult the 3CX support resources or reach out to their support team for specific instructions on how to safely and effectively disable their at-risk SQL integrations. By doing so, they will minimize exposure to the vulnerability until an official resolution is in place.

Security Issues and Attacks Involving 3CX

North Korean Hackers Compromised 3CX Environments

In March, a serious cybersecurity incident involving the 3CX platform came to light when it was discovered that the company's desktop client had been compromised. The attack was orchestrated by the North Korean hacking group UNC4736, which carried out a supply chain infiltration. This infiltration resulted in the modification of the software to distribute malware unbeknownst to the users and the company itself. The incident affected a significant number of users, reflecting the platform's extensive global reach, with its Phone System having over 12 million daily users.

Trojanized Application Led to the Compromise

It was the 3CXDesktopApp, an Electron-based desktop client, that fell victim to the treacherous trojanization. Cybersecurity companies such as CrowdStrike, SentinelOne, ESET, Palo Alto Networks, and SonicWall flagged the compromised software as malicious. Unfortunately, the detection of the malicious activity came with a delay due to 3CX's response time, taking over a week to react to customer reports. This slow reaction time potentially exacerbated the distribution of malware.

Supply Chain Attack and Its Ramifications

The ramifications of the cyberattack were extensive. Further investigations by cybersecurity firm Mandiant uncovered another layer to the breach. They found that the supply chain attack against 3CX was, in fact, a result of a prior attack on Trading Technologies—a company offering stock trading automation services. Considering 3CX's widespread usage among businesses, which include several high-profile organizations, the attack posed a critical threat to data and system integrity across various sectors.

Widespread Malware Distribution to Customers, Especially in Europe and North America

The distribution of malware via the trojanized 3CXDesktopApp primarily impacted customers in Europe and North America, where the platform possesses a large user base. Given the scope of 3CX’s clientele, which encompasses a vast array of distinguished companies and organizations, the incident underscored the vulnerability of even the most reputable and seemingly secure enterprise systems to sophisticated cyberattacks. The incident not only caused immediate security concerns but also raised questions about the robustness of the supply chain security measures that are critical to preventing such widespread cybersecurity breaches.
