CVE-2019-19507
5.3 · MEDIUMOverview
CVE-2019-19507 is a medium-severity vulnerability affecting json_pattern_validator_project json_pattern_validator. It was published on December 2, 2019 and has a CVSS 3.1 base score of 5.3 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
In jpv (aka Json Pattern Validator) before 2.1.1, compareCommon() can be bypassed because certain internal attributes can be overwritten via a conflicting name, as demonstrated by 'constructor': {'name':'Array'}. This affects validate(). Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.
Remediation
Check the references section for vendor advisories and patches from json_pattern_validator_project. Update json_pattern_validator to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
