One of them permits the attacker to craft a malicious message to the server. This channel is used to handle audio packets from the server. Information disclosure flaws were identified in the custom developers' implementation of the RDP channel. Also, privilege exploitation is needed to get full control over the system. Researchers showed that to launch either of these attacks, hackers need to exploit the chain using information-disclosure bugs and the memory-corruption issue. A malicious worker can use the computer inside the network and leverage his hold on both ends of the connection and take control of the gateway. Malicious actors can take over the system by compromising the device inside the network of the company, which leverages an oncoming being connection. Attackers get to access the server fully if vulnerabilities get exploited Knowing that vulnerabilities in FreeRDP were only patched on version 2.0.0-rc4, this means that all versions that were released before January 2020 are using vulnerable versions of FreeRDP. The company was informed and took responsibility, but the application has amassed over 10 million downloads to this date on Docker Hub, so there are many users that potentially at risk right now. The patched version was already released for Apache Guacamole, but this popular open-source program is used widely all over the world, so servers may already suffer from hacking or still be vulnerable. Besides the control, an attacker might intercept, manage, create other connected sessions.Īn attacker, who has already successfully compromised a computer inside the organization, is capable to launch an attack on the Guacamole gateway when an unsuspecting worker tries to connect to an infected machine. ![]() Researchers reveal, critical RDP vulnerabilities in the program that could lead hackers to achieve full access over the Guacamole server. ![]() This is a popular application that leaves many at risk of hacking right now. System administrators use the Apache Guacamole application to access and manage Windows and Linux machines remotely. ![]() RDP application revealed to have critical flaws that may lead to hackings. Critical flaws in the popular remote desktop application put many servers at risk since bugs can allow attackers to take full control
