Meta’s Llama Framework Flaw Exposes AI Systems to Remote Code Execution Risks

A high-severity security flaw has been disclosed in Meta’s Llama large language model ( LLM) framework that, if successfully exploited, could allow an intruder to execute arbitrary code on the llama-stack conclusion site.

The risk, tracked as , has been a CVSS report of 6.3 out of 10.0. Snyk, a supply chain security company, gave it a crucial severity rating of 9.3.

According to Avi Lumelsky, a researcher for Oligo Security,” Affected variations of meta-llama are prone to deserialization of filthy data, which means that an attacker may execute arbitrary code by sending harmful data that has been deserialized.”

The shortcoming, per the cloud security company, resides in a component called , which defines a set of API interfaces for artificial intelligence ( AI ) application development, including using Meta’s own Llama models.

It especially has to do with a remote script execution issue in the reference Python Inference API implementation, which was discovered to immediately deserialize Python objects using , a standard considered risky because it allows for random code execution when using the library to load dirty or malicious data.

Assailants could use this vulnerability by sending specially crafted harmful objects to the in” situations where the ZeroMQ outlet is exposed over the system,” Lumelsky said. ” Since recv_pyobj will unpickle these objects, an attacker could achieve arbitrary code execution (RCE ) on the host machine”.

The issue was by Meta on October 10 in edition 0.0.0.41 following concerned reporting on September 24, 2024. Additionally, it has been rebuilt using , a Python library that enables access to the ZeroMQ communication collection.

By switching to the JSON structure, the company claimed in an expert from Meta that it had fixed the risk of rural code execution when using jam as a encoding format for socket communication.

Deserialization flaws have been found in AI systems before, not just for this reason. In August 2024, Oligo a” shadow vulnerability” in TensorFlow’s Keras framework, a bypass for ( CVSS score: 9.8 ) that could result in arbitrary code execution due to the use of the unsafe marshal module.

The development comes as security researcher Benjamin Flesch disclosed a high-severity flaw in OpenAI’s ChatGPT crawler, which could be weaponized to initiate a distributed denial-of-service ( DDoS ) attack against arbitrary websites.

The issue is brought on by the” chatgpt [ .]] ]’s handling of HTTP POST requests. com/backend-api/attributions” API, which is designed to take a list of URLs as type, but neither checks if the same URL appears several times in the list nor maintains a limit on the number of hyperlinks that can be passed as type.

This opens up a situation where a malicious comedian could send thousands of hyperlinks to the victim website without trying to limit the number of connections or stop the victim from issuing record requests.

Depending on how many hyperlinks are transmitted to OpenAI, it significantly amplifications the potential for DDoS attacks, efficiently consuming the resources of the specific site. Since then, the AI firm has fixed the issue.

According to Flesch,” The ChatGPT crawler may be triggered to Attack a victim website by making an HTTP request to an unrelated ChatGPT API.” A DDoS attack will be carried out using several Microsoft Azure IP address ranges, which are being used by ChatGPT crawlers, on an innocent victim website due to this flaw in OpenAI software.

The disclosure also comes in response to a statement from Truffle Security that claims well-known AI-powered coding assistants “recommend” hard-coding Sdk keys and passwords, a difficult piece of advice that might persuade novice programmers into introducing security flaws in their projects.

LLMs are assisting in perpetuating it, most likely because they were educated in all the risky programming techniques, according to safety scholar Joe Leon.

Additionally, recent research into how the models may be abused to facilitate the digital strike lifecycle, including installing the last stage stealer payload and command-and-control, is reported.

” The virtual challenges posed by LLMs are not a trend, but an development”, Deep Instinct researcher Mark Vaitzman . ” There’s zero new it, LLMs are only making digital challenges better, faster, and more precise on a larger scale. With the assistance of a qualified drivers, LLMs can be successfully integrated into each stage of the attack cycle. As the development of the underlying technology progresses, these skills are likely to gain independence.

A new technique called , which uses its computing graph to identify design genealogy, including its architecture, type, and family, has also been by new research. The strategy utilizes a previously unreleased invasion strategy known as .

In a statement shared with The Hacker News, AI security firm HiddenLayer stated that” the names used to identify destructive problems within a mathematical graph may be modified to track and identify recurring habits, called recurring subgraphs, allowing them to determine a model’s architectural genealogy.

Understanding the concept families in use in your organization improves your general knowledge of your AI infrastructure, enabling better security posture management.
