A zero-day exploit has been impacting Check Point’s lineup of VPN products, allowing unauthorized access to corporate networks, the cybersecurity firm confirmed.
The company has yet to determine who is behind the attacks or the total number of customers impacted by the zero-day exploit, which is said by security experts to be remarkably trivial to leverage against vulnerable systems.
In a recent notification via a blog post, Check Point alerted users to a severe flaw found within its Quantum network security devices. This flaw makes it possible for a remote attacker to intercept sensitive information from a compromised system, possibly gaining entry to broader enterprise networks. The reported active exploitation of the vulnerability commenced near the end of April. A zero-day refers to a vulnerability that is exploited before the vendor can release a fix.
To mitigate the risk, Check Point issued updates and patches for customers to install immediately.
With a clientele exceeding 100,000 as listed on Check Point’s website, the company didn’t immediately respond to inquiries regarding the extent of the impact of this security flaw on its customer base.
This isn’t the first time a security firm’s products have been compromised. In fact, Check Point is the latest in a string of recent disclosures of vulnerabilities found in security products—products that are developed to protect networks against cyber threats.
Network security devices are critical as they regulate access to a network, but they are also vulnerable to security lapses that could undermine their defensive effectiveness and potentially lead to network breaches.
A few other major vendors, including Ivanti, ConnectWise, and Palo Alto Networks, have had to quickly address serious security flaws within their products following incidents where attackers targeted and compromised client systems to filch data. These defects are all considered severe, largely due to the ease with which they can be exploited.
watchTowr Labs, a cybersecurity research organization, provided an evaluation of the Check Point vulnerability and highlighted how straightforward the exploitation process is upon discovering the bug.
The vulnerability, a path-traversal flaw, could be used by an attacker to dupe a system into giving up files meant to be secure and restricted, including credentials for the device’s root-level operating system. “This is a lot more severe than what the advisory from the vendor would suggest,” mentioned Aliz Hammond, a watchTowr Labs analyst.
The U.S. cybersecurity agency, CISA, warned that this particular vulnerability has been included in its continuously updated catalog of vulnerabilities that have been known to be exploited. CISA emphasized that such exploits pose considerable dangers to governmental systems.
