This flaw affects Appsmith server instances running versions 1.98 and earlier of the \u003ccode\u003einterfaces\u003c/code\u003e package. The vulnerability stems from the direct concatenation of user-supplied table names into a SQL \u003ccode\u003eDROP TABLE\u003c/code\u003e statement without proper sanitization or validation. If an attacker can control the \u003ccode\u003etableName\u003c/code\u003e argument, they can inject arbitrary SQL commands, potentially leading to unauthorized data manipulation, exfiltration, or data loss. This is particularly concerning in scenarios where the \u003ccode\u003edropTable\u003c/code\u003e function is exposed through an API or utility accessible to users.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies an Appsmith instance running a vulnerable version (\u0026lt;= 1.98) of the \u003ccode\u003einterfaces\u003c/code\u003e package.\u003c/li\u003e\n\u003cli\u003eThe attacker discovers an endpoint or API that utilizes the \u003ccode\u003eFilterDataServiceCE.java\u003c/code\u003e\u0026rsquo;s \u003ccode\u003edropTable\u003c/code\u003e method.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious \u003ccode\u003etableName\u003c/code\u003e input containing SQL injection payload.

The primary impact is data loss, as attackers can arbitrarily drop tables within the database.

The number of affected instances is currently unknown.
