Description Preview
An attacker can exploit an improper handling of SSRF in the Dify sandbox service within langgenius/dify to inject and execute arbitrary Python code with root privileges inside the sandbox. This vulnerability, categorized under CWE-94 (Improper Control of Generation of Code), is exploitable over the network with no user interaction required. If exploited, it could allow an attacker to take over the sandbox environment, potentially deleting the entire sandbox service or causing irreversible damage. The CVSS v3.0 base score is 8.8 (High), reflecting high impacts on confidentiality, integrity, and availability, with low attack complexity and low privileges required.
Overview
Langgenius/dify contains a code injection flaw in its Dify sandbox that can be triggered via internal SSRF requests, enabling an attacker to execute arbitrary Python code with root privileges inside the sandbox. The issue affects versions up to and including 0.9.1 and poses a serious risk to the integrity and availability of the sandbox service, as well as to any systems connected to or relying on the sandbox.
Remediation
- Upgrade to the patched/recommended version released by the vendor that addresses this SSRF-based code execution vulnerability (apply the vendor’s security fix or advised release notes).
- If upgrading is not immediately possible, apply mitigations:
- Isolate the Dify sandbox service behind strict network controls and run it in a container or VM with least-privilege settings and non-root execution.
- Restrict outbound network access from the sandbox and implement strict SSRF controls, including input validation and allowlisting of destinations.
- Harden the sandbox by removing or locking down dynamic code execution pathways and ensuring that code executed inside the sandbox cannot access or escalate to host privileges.
- Implement input validation and strict sanitization for any data used to generate or execute code within the sandbox.
- Enable enhanced logging and monitoring for sandbox activity; set up alerts for anomalous outbound requests or code execution patterns.
- Rotate credentials and secrets used by the sandbox, and perform security testing (including SSRF and code-execution tests) in a staging environment after applying fixes.
- After applying fixes, verify the remediation with targeted tests and review release notes for any additional hardening recommendations from the vendor.
