Technical details
The vulnerability is a time-of-check to time-of-use (TOCTOU) race condition (CWE-367) in IBM i's SQL Query Engine that allows a local, authenticated attacker to obtain ownership of arbitrary file system objects. The race condition occurs between the moment the system checks permissions on a file and the moment it performs an operation on that file, during which an attacker can manipulate the file system. An attacker with local login privileges can exploit this window to gain ownership of files they should not have access to. IBM has released PTFs (Program Temporary Fixes) for versions 7.3, 7.4, 7.5, and 7.6 to address this vulnerability.
