CVE-2018-20062

CVE-2018-20062 is a significant vulnerability that affects the ThinkPHP framework. This flaw in software design or implementation allows for Remote Code Execution (RCE), meaning an attacker can execute arbitrary code on the targeted server remotely. The vulnerability is exploited by sending a specifically crafted GET request to the server. It is part of an exhaustive list of weaponized exploits, which are classified as having either "high" or "critical" ratings due to their ease of exploitation and the substantial impact they can have on the victim. The CVE-2018-20062 vulnerability was identified and reported in 2018. Its discovery was part of a broader effort to identify and mitigate vulnerabilities in popular software frameworks. This particular vulnerability was notable because of its potential for misuse in cyberattacks, given the widespread use of the ThinkPHP framework. This vulnerability, along with others like CVE-2014-6287, CVE-2018-1000861, CVE-2017-10271, CVE-2018-7600, CVE-2017-9791, CVE-2019-9081, PHPStudy Backdoor RCE, CVE-2017-0144, CVE-2017-0145, and CVE-2017-8464, has been weaponized and used in various cyber attacks globally. In response to the identification of this vulnerability, users of the ThinkPHP framework were advised to update their systems to a patched version that addressed the flaw. Despite these advisories, many systems remained vulnerable due to a lack of updates, making them potential targets for malicious actors. The trivial-to-exploit nature of this vulnerability coupled with the tremendous impact it could inflict on victims underlines the importance of regular system updates and robust cybersecurity practices.
