FAUCET Score

CVE-2009-4465 describes a critical information disclosure and access control vulnerability in DeluxeBB 1.3. The forum software stores sensitive user, configuration, and log data under the web root with insufficient access controls, allowing remote attackers to directly access these files and potentially gain administrative privileges. With a CVSS score of 7.5, this vulnerability is easily exploitable over the network with low attack complexity and no authentication required, leading to partial confidentiality, integrity, and availability impacts. While not listed on the KEV catalog, exploit code is publicly available on ExploitDB (EDB-10598), though there is minimal community discussion or media coverage surrounding this decade-old flaw.
