Technical details
A path traversal vulnerability (CWE-22) exists in open-iscsi's discovery handling of iSCSI Qualified Names (IQNs). The software uses received target names as directory names within the database (typically /var/lib/iscsi) without sufficient validation of prohibited ASCII characters defined in RFC 3722. A remote attacker, potentially via a Man-in-the-Middle (MITM) position or a malicious discovery server, can provide a crafted IQN containing sequences like '../../..' to create root-owned files outside the database directory. This issue is addressed in commit 668ca1df9c9a1e9bdd5c999ae1d67c9c8909237e by enforcing stricter IQN character validation.
