Name of the Vulnerable Software and Affected Versions CDATA devices versions 72408A, 9008A, 9016A, 92408A, 92416A, 9288, 97016, 97024P, 97028P, 97042P, 97084P, 97168P, FD1002S, FD1104, FD1104B, FD1104S, FD1104SN, FD1108S, FD1204S-R2, FD1204SN, FD1204SN-R2, FD1208S-R2, FD1216S-R1, FD1608GS, FD1608SN, FD1616GS, FD1616SN, FD8000

Description The issue is related to insufficiently strong encryption of data. A custom encryption algorithm is used to store encrypted passwords, which will XOR the password with a hardcoded value. This may allow a remote attacker to gain unauthorized access to protected information.

Recommendations As a temporary workaround, consider disabling the use of the custom encryption algorithm until a patch is available. Restrict access to the devices to minimize the risk of exploitation. Avoid using the hardcoded value in the encryption algorithm until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
