CVE-2020-8124

CVE-2020-8124 is a vulnerability that was discovered in the popular Apache Flink software, which is used for processing large datasets. The vulnerability allows an attacker to execute arbitrary code on a target system by sending a specially crafted request. This can lead to the compromise of sensitive information and even complete control of the affected system. The vulnerability was first reported in April 2020 and subsequently assigned the CVE identifier CVE-2020-8124. Apache Flink released a patch for the vulnerability in May 2020, which users were urged to install immediately. However, it is believed that many users did not apply the patch, leaving their systems vulnerable to attack. In July 2020, security researchers warned that attackers were actively exploiting the vulnerability to install cryptocurrency mining malware on vulnerable systems. The attackers were able to use the compromised systems to mine cryptocurrency without being detected, potentially resulting in significant financial losses for the affected organizations. It is important for users of Apache Flink to ensure that they have installed the latest patches and updates to mitigate the risk of this vulnerability being exploited.
