CVE-2020-17496 is a critical remote command execution (RCE) vulnerability affecting vBulletin versions 5.5.4 through 5.6.2, stemming from an incomplete fix for CVE-2019-16759. This flaw allows unauthenticated attackers to execute arbitrary commands by crafting specific subWidgets data within an ajax/render/widget_tabbedcontainer_tab_panel request. With a CVSS score of 9.8 (Critical) and a FAUCET Risk Score of 100/100, it poses a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. The vulnerability is actively exploited in the wild, with readily available Metasploit modules and Nuclei templates, and has garnered significant community discussion and media coverage, including its use by the Gitpaste-12 worm botnet.
