AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-55282 is a critical privilege escalation vulnerability in the aiven-db-migrate tool versions prior to 1.0.7. It occurs because the database migration process does not restrict the PostgreSQL search_path, allowing an attacker with high privileges to override the pg_catalog schema. This enables the attacker to execute untrusted operators as a superuser during migration from an untrusted source server, effectively escalating their privileges inside the PostgreSQL database. [1]
How can this vulnerability impact me? :
This vulnerability can allow an attacker with existing high privileges to escalate to superuser within PostgreSQL databases during migration. This leads to a complete compromise of the database's confidentiality, integrity, and availability, as the attacker can execute arbitrary superuser-level commands. The attack is network-based, has low complexity, requires no user interaction, and results in a scope change affecting critical security properties. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection involves checking if your environment is running aiven-db-migrate versions prior to 1.0.7 and if migrations are performed from untrusted source servers. You can verify the installed version by running: `aiven-db-migrate --version` or checking the package version in your environment. Additionally, to detect if the vulnerable behavior occurs, you can monitor PostgreSQL logs for unexpected superuser privilege escalations during migrations. There is no specific command provided to detect the vulnerability directly, but reviewing migration source trustworthiness and version is key. [1]
What immediate steps should I take to mitigate this vulnerability?
The immediate mitigation is to upgrade aiven-db-migrate to version 1.0.7 or later, where the vulnerability is fixed. Additionally, avoid performing database migrations from untrusted source servers unless using the patched version. The fix involves explicitly setting the PostgreSQL `search_path` to an empty string during connection setup to prevent privilege escalation. [1, 2]
