Technical Analysis
REMEDIATION: Update to one of the following versions, or a newer patched version: 2.5.16, 2.6.2, 2.7.2, 2.8.1, 2.9.1, 3.0.1, 3.1.1, 3.2.1, 3.3.1, 3.4.1, 3.5.1, 3.6.1, 3.7.2, 3.8.1, 3.9.1, 4.0.1, 4.1.1, 4.2.1, 4.3.1, 4.4.3, 4.5.3, 4.6.1, 4.7.1, 4.8.1, 4.9.2, 5.0.1, 5.1.1, 5.2.1, 5.3.2, 5.4.1, 5.5.1 --- 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.
