CVE-2006-0174

21
FAUCET Score

CVE-2006-0174 describes an information disclosure vulnerability in Hummingbird Collaboration (versions 5.21 and earlier). A remote, authenticated attacker can directly request the "hc" component, causing error messages or cookies to reveal sensitive internal network information, such as intranet IP addresses and valid parameter values. This vulnerability has a CVSS score of 4.0, indicating a medium severity due to its network attack vector and low attack complexity, potentially leading to a partial loss of confidentiality. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry (EDB-27062) exists, and there is minimal community discussion or media coverage.
