Name of the Vulnerable Software and Affected Versions IBM QRadar SIEM versions 7.3 through 7.4

Description The issue is related to insufficiently robust data encryption in the system. This could allow a remote attacker to gain unauthorized access to protected information. The problem stems from the use of weaker than expected cryptographic algorithms, which could enable an attacker to decrypt highly sensitive information.

Recommendations For versions 7.3 and 7.4, update to a version that uses stronger cryptographic algorithms to mitigate the risk of data decryption by attackers. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
