Command injection in gh-ost

Gh-ost version <= 1.1.2 allows users to inject DSN strings via the -database parameter.

This is a low severity vulnerability as the attacker must have access to the target host or trick an administrator into executing a malicious gh-ost command on a host running gh-ost, plus network access from host running gh-ost to the attack's malicious MySQL server.

Impact

This issue may lead to arbitrary local file read.

Patches

Fixed in 1.1.3+.

Workarounds

None
