Short explanation

On Unix-like systems, psqlODBC creates log files with default permissions at a predictable path and follows symbolic links. S0

Why does it matter?

A local user can read query text and data from other users' logs or append log data to an arbitrary file with the victim's privileges. S0

What should be done?

  • Follow vendor advisories S0
  • Update psqlODBC version S0 S1
  • Review logging configurations S0 S1

Show the technical text from the sources

On Unix-like systems, when logging is enabled, psqlODBC creates its log files in /tmp by default, named from the program name, user name, and process ID, with the default permissions, typically world-readable, and follows symbolic links when opening them. A local user can read query text and data from another user's logs, and can place a symbolic link at the predictable path so that the driver appends log data to a file of the attacker's choosing with the victim's privileges. Versions before psqlODBC 18.00.0006 are affected.
