Overview<\/strong><\/p>\n

One of the most notorious vulnerabilities in web applications is SQL Injection, which can potentially affect any software that uses an SQL database. CVE-2025-47490 is one such vulnerability that affects the Rustaurius Ultimate WP Mail plugin. This vulnerability is significant due to its high impact on system integrity and confidentiality, as it could lead to system<\/a> compromise or data leakage if successfully exploited. As such, it is crucial for developers, administrators, and end-users alike to understand this vulnerability and implement necessary mitigation strategies<\/a>.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-47490
\nSeverity: High (8.5 CVSS Severity Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System compromise<\/a> or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Rustaurius Ultimate WP Mail | n\/a through 1.3.4<\/p>\n

How the Exploit Works<\/strong><\/p>\n

An attacker exploiting this vulnerability would send specially crafted SQL commands<\/a> through user inputs, which would then be executed by the application’s database. This is due to the application’s improper neutralization<\/a> of special elements used in an SQL command. As a result, an attacker could gain unauthorized access to sensitive information<\/a>, modify data, or even gain control of the affected system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP request carrying the SQL injection<\/a> payload:<\/p>\n

POST \/wpmail\/send HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"recipient\": \"[email protected]\", \"subject\": \"Test\", \"message\": \"test'; DROP TABLE users;--\" }<\/code><\/pre>\n
In this example, the SQL command `DROP TABLE users;–` is injected<\/a> into the “message” field of the request. The semicolon denotes the end of one command and the start of another, while the double-dash `–` signifies the start of a comment, effectively ignoring any syntax after it. If the application does not sanitize this input<\/a>, the SQL command will be executed, leading to the “users” table being deleted from the database.<\/p>\n
Mitigation<\/strong><\/p>\n
The official mitigation guidance for CVE-2025-47490 is to apply the vendor patch. If a patch is not immediately available or feasible to apply, a temporary mitigation strategy could be to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block SQL Injection<\/a> attempts. Additionally, best practice measures against SQL Injection<\/a> should also be followed, such as using prepared statements or parameterized queries, escaping all user-supplied input, and limiting the privileges of database accounts used by web applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
