According to its self-reported version number, IBM Db2 is affected by multiple vulnerabilities:
IBM Db2 is affected by an information disclosure vulnerability when using the LOAD utility as under certain circumstances the LOAD utility does not enforce directory restrictions. (CVE-2021-20373)
IBM Db2 is affected by an information disclosure vulnerability as a user with DBADM authority is able to access other databases and read or modify files. (CVE-2021-29678)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
