Synopsis

The remote database server is affected by multiple vulnerabilities

Description

According to its version, the installation of IBM DB2 running on the remote host is 11.5 prior to 11.5.6 FP0. It is, therefore, affected by multiple vulnerabilities including the following:
- IBM DB2 is affected by a flaw which could allow an unauthenticated, local user to to access and change configuration of the database. This is due to a race condition of a symbolic link. (CVE-2020-4885)

- An arbitrary file write vulnerability exists in IBM DB2 due to improper group permissions. An authenticated, remote attacker can exploit this to write arbitrary files on the remote host.
(CVE-2020-4945)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update IBM DB2 version to 11.5.6 FP0 or later.
