CVE-2023-43042

20
FAUCET Score

CVE-2023-43042 describes a critical vulnerability in IBM SAN Volume Controller, IBM Storwize, IBM FlashSystem, and IBM Storage Virtualize 8.3 products, where a privileged user account utilizes a default password. This allows an unauthenticated attacker to gain full access to sensitive information due to the network-based attack vector and low attack complexity, resulting in a CVSS score of 7.5 (High). While no active exploitation, public exploit code, or significant community discussion has been observed, the presence of a default password for a privileged user poses a significant risk to the confidentiality of affected systems.
