CVE-2000-1177

25
FAUCET Score

CVE-2000-1177 describes a file existence and user ID disclosure vulnerability in several Big Brother (BB) scripts (bb-hist.sh, bb-histlog.sh, bb-hostsvc.sh, bb-rep.sh, bb-replog.sh, and bb-ack.sh) in versions prior to 1.5d3. An unauthenticated remote attacker can exploit this by manipulating the HISTFILE parameter. This medium-severity vulnerability has a CVSS score of 5.0, indicating a network-based attack with low complexity, resulting in partial confidentiality impact without affecting integrity or availability. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry confirms the existence of proof-of-concept code for file existence disclosure, though community discussion and media coverage are minimal.
