VAR-200803-0434

Vulnerability from variot - Updated: 2025-04-10 23:25

RaidSonic NAS-4220-B with 2.6.0-n(2007-10-11) firmware stores a partition encryption key in an unencrypted /system/.crypt file with base64 encoding, which allows local users to obtain the key. RaidSonic NAS-4220-B is prone to a vulnerability that can compromise encrypted data. This issue occurs because the key used by the device to encrypt hard-drive data is stored insecurely in the configuration partitions of each drive. Attackers with physical access to the NAS can exploit this issue to decrypt potentially sensitive information stored on the hard disks. This issue affects NAS-4220-B running firmware 2.6.0-n(2007-10-11). Other devices and firmware versions may also be affected. ----------------------------------------------------------------------

A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched.
