CVE-2021-3833

30
FAUCET Score

CVE-2021-3833 affects Artica Integria IMS, stemming from a flawed password comparison mechanism during login. The system uses a loose comparator ("==") for MD5 password hashes, allowing an attacker to bypass authentication with specially crafted passwords. This critical vulnerability (CVSS 9.8) has a low attack complexity and requires no user interaction, potentially leading to full compromise of confidentiality, integrity, and availability. While no public exploits or active exploitation have been observed, and community discussion is minimal, the inherent flaw presents a significant risk.
