Name of the Vulnerable Software and Affected Versions IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) versions 9.7, 10.1, 10.5, 11.1, and 11.5

Description The issue is related to weak file permissions, allowing a local user to read and write specific files. It is also associated with inadequate access control, which could enable an attacker to read and write arbitrary files.

Recommendations For versions 9.7, 10.1, 10.5, 11.1, and 11.5, consider restricting file access to minimize the risk of exploitation until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
