CVE-2011-4924

22
FAUCET Score

CVE-2011-4924 describes a cross-site scripting (XSS) vulnerability in multiple versions of Zope 2.x and 3.x, stemming from insufficient sanitization of error messages. This medium-severity vulnerability (CVSS 6.1) allows unauthenticated remote attackers to inject arbitrary web script or HTML via user interaction, potentially leading to information disclosure or defacement. While the vulnerability is publicly known, there is no evidence of active exploitation, readily available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage. This issue is noted as an incomplete fix for a previous vulnerability, CVE-2010-1104.
