LangChain < 0.2.9 SSRF

high Nessus Plugin ID 209518

Synopsis

The remote host contains a machine learning library that is affected by a server side request forgery vulnerability.

Description

The remote host contains a langchain version that is prior to 0.2.9. It is, therefore, affected by a Server-Side Request Forgery vulnerability in the Web Research Retriever component in langchain-community (langchain-community.retrievers.web_research.WebResearchRetriever). The vulnerability arises because the Web Research Retriever does not restrict requests to remote internet addresses, allowing it to reach local addresses. This flaw enables attackers to execute port scans, access local services, and in some scenarios, read instance metadata from cloud environments. The vulnerability is particularly concerning as it can be exploited to abuse the Web Explorer server as a proxy for web attacks on third parties and interact with servers in the local network, including reading their response data. This could potentially lead to arbitrary code execution, depending on the nature of the local services. The vulnerability is limited to GET requests, as POST requests are not possible, but the impact on confidentiality, integrity, and availability is significant due to the potential for stolen credentials and state-changing interactions with internal APIs.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to LangChain 0.2.9 or later.
