Underlying weakness

CWE-89: Improper Neutralization of Special Elements used in an SQL Command

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.

Affected products

  • Blueyonder Postgraas Server: before 2.0.0; 2.0.0 beta1; 2.0.0 beta2
