CVE-2023-32305 – aiven-extras PostgreSQL Privilege Escalation Through Overloaded Search Path
https://notcve.org/view.php?id=CVE-2023-32305
aiven-extras is a PostgreSQL extension. Versions prior to 1.1.9 contain a privilege escalation vulnerability, allowing elevation to superuser inside PostgreSQL databases that use the aiven-extras package. The vulnerability leverages missing schema qualifiers on privileged functions called by the aiven-extras extension. A low privileged user can create objects that collide with existing function names, which will then be executed instead. Exploiting this vulnerability could allow a low privileged user to acquire `superuser` privileges, which would allow full, unrestricted access to all data and database functions. • https://github.com/aiven/aiven-extras/commit/8682ae01bec0791708bf25791786d776e2fb0250 https://github.com/aiven/aiven-extras/security/advisories/GHSA-7r4w-fw4h-67gp https://security.netapp.com/advisory/ntap-20230616-0006 • CWE-20: Improper Input Validation CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
