CVE-2023-1370

Description

A flaw was found in the json-smart package. This security flaw occurs when reaching a ‘[‘ or ‘{‘ character in the JSON input, and the code parses an array or an object, respectively. The 3PP does not have any limit to the nesting of such arrays or objects. Since nested arrays and objects are parsed recursively, nesting too many of them can cause stack exhaustion (stack overflow) and crash the software.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)

Resources including CPU, memory, and stack memory could be rapidly consumed or exhausted, eventually leading to an exit or crash.

Confidentiality

Technical Impact: Read Application Data

In some cases, an application's interpreter might kill a process or thread that appears to be consuming too much resources, such as with PHP's memory_limit setting. When the interpreter kills the process/thread, it might report an error containing detailed information such as the application's installation path.
