CVE-2022-35942 Detail

Description

Improper input validation on the `contains` LoopBack filter may allow for arbitrary SQL injection. When the extended filter property `contains` is permitted to be interpreted by the Postgres connector, it is possible to inject arbitrary SQL which may affect the confidentiality and integrity of data stored on the connected database. A patch was released in version 5.5.1. This affects users who does any of the following: - Connect to the database via the DataSource with `allowExtendedProperties: true` setting OR - Uses the connector's CRUD methods directly OR - Uses the connector's other methods to interpret the LoopBack filter. Users who are unable to upgrade should do the following if applicable: - Remove `allowExtendedProperties: true` DataSource setting - Add `allowExtendedProperties: false` DataSource setting - When passing directly to the connector functions, manually sanitize the user input for the `contains` LoopBack filter beforehand.

CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  10.0 CRITICAL
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  9.3 CRITICAL
Vector:  CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
