Description

The 404 Redirection Manager plugin version 1.0 for WordPress contains an unauthenticated SQL injection vulnerability that allows remote attackers to execute arbitrary SQL queries by injecting malicious code through unsanitized user input. Attackers can craft GET requests with SQL injection payloads to manipulate database queries and extract sensitive information from the WordPress database.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
