While most of the VNC memory corruption vulnerabilities disclosed by the researchers to the development teams were fixed, in some cases they haven't been addressed to this day. This is the case of TightVNC 1. X, whose developers said that they won't fix the found security issues since the software's first version is "no longer support the first version of their system [.. X commercial product. Cheremushkin found heap-based buffer overflows in the LibVNC library that could potentially allow attackers "to bypass ASLR and use overflow to achieve remote code execution on the client.

TightVNC came with a null pointer dereference leading to Denial of System DoS states, as well as two heap buffer overflows and a global buffer overflow that could lead to remote code execution. As already mentioned above, these security issues will not be fixed. A stack buffer overflow vulnerability was discovered in the TurboVNC server the might lead to remote code execution, although it requires authorization on the server or control over the VNC client before the connection.

When it comes to UltraVNC, the researcher says that he was able to discover "an entire 'zoo' of vulnerabilities in UltraVNC — from trivial buffer overflows in strcpy and sprintf to more or less curious vulnerabilities that can rarely be encountered in real-world projects.

The CVE one is assigned to multiple heap buffer overflow vulnerabilities that can result in remote code execution. The full list of discovered VNC vulnerabilities found by Kaspersky's Pavel Cheremushkin are listed in the table below:.

How to spot dangerous links sent in messages and other tricks scammers use to steal your data. Solutions for:. Where we found the vulnerabilities Our experts looked at four common open-source VNC implementations: LibVNC — a library, that is, a set of ready-made code snippets on which basis developers can create apps; LibVNC is used, for example, in systems that allow remote connections to virtual machines, as well as iOS and Android mobile devices.

TightVNC 1. X — an application recommended by vendors of industrial automation systems for connecting to a human—machine interface HMI. What the vulnerabilities are and how they can be exploited VNC applications consist of two parts: a server installed on the computer to which your employee connects remotely, and a client running on the device from which it connects.

Some vulnerabilities fixed, but not all Our CERT folks reported the bugs to the developers of the respective libraries and applications. What action should businesses take? Check which devices can connect remotely, and block remote connections if not required. Inventory all remote access applications — not just VNC — and check that their versions are up-to-date. If you have doubts about their reliability, stop using them. If you intend to continue deploying them, be sure to upgrade to the latest version.

Protect your VNC servers with a strong password. This will make attacking them far harder. Do not connect to untrusted or untested VNC servers. In industrial enterprise environments, use a specialized security solution for industrial automation systems, for example, Kaspersky Industrial CyberSecurity.

To protect your business, use a robust security solution. An excellent choice is Kaspersky Endpoint Security for Business.
