CVE-2018-1132: Opendaylight Sdninterfaceapp: Improper Neutralization of Special Elements used in an SQL Command

CVE-2018-1132 is rated critical with a CVSS v3.0 base score of 9.8 and affects Opendaylight Sdninterfaceapp. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

A flaw was found in Opendaylight's SDNInterfaceapp (SDNI). Attackers can SQL inject the component's database (SQLite) without authenticating to the controller or SDNInterfaceapp. SDNInterface has been deprecated in OpenDayLight since it was last used in the final Carbon series release. In addition to the component not being included in OpenDayLight in newer releases, the SDNInterface component is not packaged in the opendaylight package included in RHEL.

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

  • Opendaylight Sdninterfaceapp: up to and including carbon-sr4
