What is CVE-2024-27130?

CVE-2024-27130 is a critical vulnerability found in the QNAP operating system that affects a range of versions. This vulnerability occurs due to a buffer copy operation that does not adequately check the size of the input data. If successfully exploited, attackers could execute arbitrary code through network interactions, thereby compromising the affected systems. Since QNAP appliances are commonly used for network-attached storage and other applications, this vulnerability poses a significant risk to organizations that rely on these devices for data management and security.

Technical Details

The vulnerability is categorized as a buffer copy without size checking, which means that it can lead to memory corruption if an attacker sends a specially crafted input to the system. The flaw resides in the way the operating system processes incoming data, allowing for potential exploitation via network protocols. To mitigate this vulnerability, QNAP has released updates in QTS 5.1.7.2770 and later versions that address the underlying issue.

Impact of the Vulnerability

  1. Remote Code Execution: Exploitation of this vulnerability could lead to remote code execution, giving attackers full control over the affected devices. This could result in unauthorized access to sensitive data and the ability to perform malicious activities on the network.

  2. Data Leakage and Loss: If an attacker successfully executes code on a vulnerable system, it can lead to the exfiltration of confidential information stored on the QNAP device. This compromises both the integrity and confidentiality of data.

  3. Potential for Further Attacks: Once an attacker gains access to a vulnerable system, they can use it as a foothold to launch additional attacks within the network, potentially spreading malware, including ransomware, and compromising further systems connected to the network.

Affected Version(s)

QTS < 5.1.7.2770 build 20240520

QuTS hero < h5.1.x

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
