Synopsys: Data Poisoning Vulnerabilities Found in EmbedAI Application

The Synopsys Cybersecurity Research Center (CyRC) has exposed a Data Poisoning vulnerability in the EmbedAI Application. EmbedAI allows users to interact with documents by utilising the capabilities of large language models (LLM).

The EmbedAI application is susceptible to security issues that enable Data Poisoning attacks. This weakness could result in the application becoming compromised, leading to unauthorised entries or data poisoning attacks, which are delivered by a CSRF vulnerability due to the absence of a secure session management implementation and weak CORS policies weakness.

Exploitation
An attacker can direct a user to a malicious webpage that exploits a CSRF vulnerability within the EmbedAI application. By leveraging this CSRF vulnerability, the attacker can deceive the user into inadvertently uploading and integrating incorrect data into the application’s language model.

Affected Software

  • EmbedAI "main" branch

Impact
The exploitation of this vulnerability affects the immediate functioning of the model and can have long-lasting effects on its credibility and the security of the systems that rely on it. This can manifest in various ways, including the spread of misinformation, introduction of biases, degradation of performance, and potential for denial-of-service attacks.

  • CVSS Base Score: 7.3 (High)

  • CVSS 3.1 Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H

Remediation
The CyRC reached out to the developers but has not received a response within the 90-day timeline dictated by our responsible disclosure policy. The CyRC recommends removing the applications from networks immediately.

Discovery credit
This vulnerability was discovered by Mohammed Alshehr, security researcher at Synopsys Software Integrity Group.
