CVE-2020-21495 describes a cross-site scripting (XSS) vulnerability in Xiuno BBS version 4.0.4, specifically within the /admin/?setting-base.htm component. An unauthenticated attacker can exploit this by injecting malicious web scripts or HTML into the 'sitename' parameter. This vulnerability carries a CVSS score of 6.1 (Medium), indicating that it can be exploited remotely with low complexity, requiring user interaction, and potentially leading to limited impact on confidentiality and integrity. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the risk remains due to the potential for arbitrary script execution.
