DescriptionCVE.org

A vulnerability was identified in modelscope agentscope up to 1.0.18. Affected by this issue is the function _parse_url/prepare_image/openai_audio_to_text of the file src/agentscope/tool/_multi_modality/_openai_tools.py of the component Cloud Metadata Endpoint. Such manipulation of the argument image_url/audio_file_url leads to server-side request forgery. The attack may be performed from remote. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Server-side request forgery (SSRF) in ModelScope AgentScope up to version 1.0.18 allows remote unauthenticated attackers to manipulate image_url and audio_file_url parameters in the _parse_url, prepare_image, and openai_audio_to_text functions, enabling arbitrary HTTP requests from the affected server. The vulnerability has publicly available exploit code and affects the Cloud Metadata Endpoint component. …

Vulnerability AssessmentAI

Exploitation The vulnerability requires that the AgentScope multi-modality OpenAI tools component is deployed and accessible to the attacker (network-reachable endpoint). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment CVSS 6.9 with AV:N/AC:L/PR:N/UI:N indicates network-accessible exploitation with no authentication or user interaction required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker sends a POST request to an AgentScope instance with a malicious image_url parameter pointing to an internal service, such as http://169.254.169.254/latest/meta-data (AWS metadata endpoint) or http://localhost:8080/admin/config. The vulnerable _parse_url or prepare_image function processes this URL without validation and makes a server-side HTTP request to fetch the resource. …
Remediation Upgrade AgentScope to a version newer than 1.0.18 if a patched release becomes available from the ModelScope project. … Detailed patch versions, workarounds, and compensating controls in full report.
