Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures (CVE) system has identified a serious security vulnerability in the Aiven database migration tool, aiven-db-migrate. The vulnerability, designated as CVE-2025-55283, is a privilege escalation vulnerability that enables the elevation to superuser inside PostgreSQL databases during a migration from an untrusted source server. The vulnerability is particularly significant because it can lead<\/a> to potential system compromise or data leakage, two outcomes that can have serious consequences for organizations that rely on the integrity and security of their databases.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-55283
\nSeverity: Critical (9.1)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Potential system compromise<\/a> or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

aiven-db-migrate | Prior to 1.0.7<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by taking advantage of the psql’s functionality of executing commands<\/a> embedded in a dump from the source server. When aiven-db-migrate is used to migrate data from an untrusted source server, it opens up a potential attack vector for privilege escalation<\/a>. An attacker could embed malicious commands in the dump which will be executed by psql during the migration, potentially leading to the attacker gaining superuser privileges<\/a>.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited. This pseudocode describes the process of creating a dump with a malicious command embedded:<\/p>\n

CREATE TABLE malicious_table AS SELECT pg_catalog.pg_ls_dir('..');\nCOPY (SELECT * FROM malicious_table) TO '\/tmp\/malicious_dump.sql';<\/code><\/pre>\n
In this pseudocode, a new table is created that executes a command<\/a> to list the parent directory of the current directory. The output of this command is then copied to a dump file<\/a>. When this dump is imported during a migration, the command will be executed, potentially leading to privilege escalation<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
The vulnerability has been fixed in version<\/a> 1.0.7 of aiven-db-migrate. Therefore, users are strongly advised to update to this version or later. If updating is not immediately possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure. These systems can potentially detect and block attempts to exploit this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
