CVE-2018-1053 vulnerability in PostgreSQL and Other Products
Published on February 9, 2018
In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.
Weakness Type
Insecure Temporary File
Creating and using insecure temporary files can leave application and system data vulnerable to attack.
