Description
An issue exists in the
omclickhouse action where output templates fail to escape backslash characters during the construction of SQL queries. This allows a remote attacker, without authentication, to send crafted log messages to a ClickHouse-forwarding ruleset to inject or alter SQL commands. This could lead to unauthorized database modification or data disclosure. Only deployments utilizing the omclickhouse action are impacted.Recommendations
Restrict the use of the
omclickhouse action until a fix is available. Found an issue in the description? Have something to add? Feel free to write us 👾
