TIBCO Security Advisory: June 9, 2020 - TIBCO Managed File Transfer Platform Server for IBM i
- TIBCO Managed File Transfer Platform Server for IBM i versions 7.1.0 and below
- TIBCO Managed File Transfer Platform Server for IBM i version 8.0.0
The following component is affected:
- file transfer
The component listed above contains a vulnerability that theoretically allows an attacker to perform unauthorized network file transfers to and from the file system accessible to the affected component. This vulnerability is exploitable when the configuration option 'Require Node Resp' is set to 'No'. In the event of a successful exploit, the attacker could theoretically read and write any file on the file system accessible to the affected component, thus fully affecting the confidentiality, integrity, and availability of the operating system hosting the deployment of the affected system.
The impact of this vulnerability includes the possibility that an attacker could gain access to the contents of files they are otherwise not authorized to see, and modify files they otherwise should not be able to change, and affect the availability of the hosting system, by way of damaging critical system files.
CVSS v3 Base Score: 10.0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)
TIBCO has released updated versions of the affected systems which address this issue:
- TIBCO Managed File Transfer Platform Server for IBM i versions 7.1.0 and below update to version 7.1.1 or higher
- TIBCO Managed File Transfer Platform Server for IBM i version 8.0.0 update to version 8.0.1 or higher
For an alternate remediation, change the configuration option 'Require Node Resp' to 'Yes', and also explicitly add all of the nodes accessing the affected system that have not yet been added to the configuration.
