Assigner: TuranSec

Description

HashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the Git deployer component. GitDeployer.pullRepo in src/Server/Entity/Deployer/GitDeployer.js executes AppService.exec, interpolating the configured branch value directly into a shell command with no escaping.

Attack-Flow Graph

Executive Summary

HashBrown CMS through 1.4.6 has an OS Command Injection vulnerability in the Git deployer component. The GitDeployer.pullRepo() function executes a shell command with user-controlled input without proper escaping. Attackers can inject malicious commands via the branch configuration, which executes automatically during deployer operations like media uploads or content saves.

Detection Guidance

Check for unauthorized Git deployer configurations in HashBrown CMS projects. Inspect branch names for shell metacharacters like ;, &&, |, backticks, or $(). Look for unexpected system commands in logs or process execution.

Impact Analysis

An attacker with access to configure Git deployer settings could execute arbitrary commands on the server. This could lead to full system compromise, data theft, or unauthorized modifications. The attack is persistent as the malicious branch value remains active across deployer operations.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's security rules. Organizations using HashBrown CMS may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Update HashBrown CMS to the latest version beyond 1.4.6. Remove or disable the Git deployer component if unused. Restrict write access to deployer settings to trusted users only.
