Technical Analysis
REMEDIATION: Update to one of the following versions, or a newer patched version: 3.7.23, 3.8.23, 3.9.21, 4.0.20, 4.1.20, 4.2.17, 4.3.13, 4.4.12, 4.5.11, 4.6.8, 4.7.7, 4.8.3 --- 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.
