CVE-1999-0383

19
FAUCET Score

CVE-1999-0383 describes a critical vulnerability in ACC Tigris, where the product allows public access without requiring authentication. This flaw presents a high-severity risk (CVSS 7.5) due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, the vulnerability's age and the lack of modern exploit intelligence tools suggest it may be less relevant for current threats.
