CVE-2023-43794

Nocodb contains SQL injection vulnerability, that allows an authenticated attacker with creator access to query the underlying database.

Product

nocodb/nocodb

Tested Version

0.109.2

Details

SQL injection in SqliteClient.ts (GHSL-2023-141)

By supplying a specially crafted payload to the given below parameter and endpoint, an attacker can inject arbitrary SQL queries to be executed. Since this is a blind SQL injections, an attacker may need to use time-based payloads which would include a function to delay execution for a given number of seconds. The response time indicates, whether the result of the query execution was true or false. Depending on the result, the HTTP response will be returned after a given number of seconds, indicating TRUE, or immediately, indicating FALSE. In that way, an attacker can reveal the data present in the database.

The triggerList method creates a SQL query using the user-controlled table_name parameter value from the tableCreate endpoint.

async triggerList(args: any = {}) {
  const _func = this.triggerList.name;
  const result = new Result();
  log.api(`${_func}:args:`, args);

  try {
    args.databaseName = this.connectionConfig.connection.database;

    const response = await this.sqlClient.raw(
      `select *, name as trigger_name from sqlite_master where type = 'trigger' and tbl_name='${args.tn}';`,
    );
[...]

Disclosure Policy

This report is subject to our coordinated disclosure policy.

This issue may lead to Information Disclosure.

Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.

CVE-2023-43794 has a CVSS score of 6.5 (Medium). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.111.0); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2023-43794? CVE-2023-43794 is a medium-severity SQL injection vulnerability in nocodb (npm), affecting versions < 0.111.0. It is fixed in 0.111.0. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
2. How severe is CVE-2023-43794? CVE-2023-43794 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of nocodb are affected by CVE-2023-43794? nocodb (npm) versions < 0.111.0 is affected.
4. Is there a fix for CVE-2023-43794? Yes. CVE-2023-43794 is fixed in 0.111.0. Upgrade to this version or later.
5. Is CVE-2023-43794 exploitable, and should I be worried? Whether CVE-2023-43794 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2023-43794 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2023-43794? Upgrade nocodb to 0.111.0 or later.
