Vulnerability Overview

When deleting a date in the Xllentech English Islamic Calendar WordPress plugin before 2.6.8, the year_number and month_number POST parameters are not sanitised, escaped or validated before being used in a SQL statement, leading to SQL injection.

Technical Analysis

REMEDIATION: Update to version 2.6.8, or a newer patched version --- IDENTIFIER: CWE-89 (Improper 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.
