CVE-2021-41318

33
FAUCET Score

CVE-2021-41318 describes a stored Cross-Site Scripting (XSS) vulnerability in Progress WhatsUp Gold versions prior to 21.1.0, where an application endpoint inadequately sanitizes user input. This flaw allows an unauthenticated attacker to execute arbitrary code within a victim's browser. With a CVSS score of 6.1 (Medium), the attack requires user interaction (UI:R) but can be executed over the network (AV:N) with low complexity (AC:L), potentially leading to limited confidentiality and integrity impacts. While not listed on the KEV catalog and lacking Metasploit or Nuclei modules, an exploit is publicly available on ExploitDB (EDB-50366), though there is minimal community discussion or media coverage surrounding this CVE.
