CyberRota Analysis

AI-Generated

Versions of SigNoz prior to 0.142.0 are vulnerable due to improper handling of user-supplied telemetry field-key names in the v5 query_range API, enabling authenticated users to perform SQL injection attacks. This vulnerability allows attackers with a Viewer role or higher to execute arbitrary ClickHouse SQL queries, potentially leading to unauthorized access to system tables and data exfiltration. Organizations using affected versions should prioritize patching to mitigate the risk of data breaches.

Original NVD Description

SigNoz versions 0.87.0 before 0.142.0 fail to escape user-supplied telemetry field-key names in the v5 query_range API, allowing authenticated users to inject SQL. Attackers with Viewer role or higher can embed backticks and quotes in field names to break out of identifiers and string literals, executing arbitrary ClickHouse SQL to read system tables and exfiltrate data.
