Sequelize: SQL Injection (Oracle DB)

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published

Sequelize is a Node.js ORM tool. Prior to 6.37.4, SQL injection is possible with strings only if dialect is set to oracle. The escape function defined in sql-string.js does not escape quotes if the value starts with TO_TIMESTAMP or TO_DATE. In the Oracle dialect, when val is a string and starts with TO_TIMESTAMP or TO_DATE, escape returns val directly instead of replacing single quotes. An attacker can inject arbitrary SQL expressions through an application value that reaches this escape path. This issue is fixed in version 6.37.4.

### Summary SQL Injection is possible with strings only **if dialect is set to `oracle`**. The vulnerability was confirmed on Sequelize v6.37.3. ### Details The `escape` function defined in `sql-string.js` does not escape quotes if the value starts with `TO_TIMESTAMP` or `TO_DATE`. ```javascript } else if (dialect === 'oracle' && typeof val === 'string') { if (val.startsWith('TO_TIMESTAMP') || val.startsWith('TO_DATE')) { return val; } val = val.replace(/'/g, "''"); } ``` ### PoC Suppose the application has the following code: ```javascript var result = await models.Student.findOne({ where: { firstName: req.query.firstName } }); ``` An attacker can inject arbitrary sql expressions. `http://host/path?firstName=TO_DATE('0','Y')||'' OR 1=1--` The resulted SQL will be: ```SQL SELECT ... WHERE "Student"."firstName" = TO_DATE('0','Y')||'' OR 1=1-- ORDER BY "Student"."id" OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY; ``` ### Impact Data theft and tampering.
