RSA BSAFE Micro Edition Suite Covert Timing Channel Vulnerability [CVE-2018-11057 ]

CVE Number – CVE-2018-11057

A vulnerability in RSA BSAFE Micro Edition Suite could allow an unauthenticated, remote attacker to access sensitive information on a targeted system.The vulnerability is due to cryptographic issues in the affected software, which could be leveraged to conduct Bleichenbacher-style covert timing channel attacks. An attacker who can capture traffic between the targeted system and another system or between a user and the targeted system could exploit this vulnerability to access sensitive information, such as RSA keys. A successful exploit could be used to conduct further attacks.RSA has confirmed the vulnerability and released software updates.

Analysis

• To exploit this vulnerability, the attacker must be able to capture traffic between the targeted system and another system or between a user and the targeted system. It is likely that the attacker would need access to the same internal network as these systems to achieve a successful exploit.

Safeguards

• Administrators are advised to apply the appropriate updates.Administrators are advised to allow only trusted users to have network access.Administrators are advised to run both firewall and antivirus applications to minimize the potential of inbound and outbound threats.Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.Administrators can help protect affected systems from external attacks by using a solid firewall strategy.Administrators are advised to monitor affected systems.
