Horizon Alert
Summary of the vulnerability and why it matters
The AMMOS Instrument Toolkit, used for mission control and satellite data handling, has a vulnerability in its Binary Stream Capture component. This allows an unauthenticated attacker to potentially write to arbitrary files on the system by exploiting a path traversal weakness in an HTTP API. The main concern is confirming if this specialized software is in use and exposed to such risks within the organization.
- Software can be tricked into writing to wrong files.
- Confirms relevance and exposure of specialized systems.
- Assess if this specific tool is deployed.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by sending specially crafted requests to the Binary Stream Capture (BSC) component of the AMMOS Instrument Toolkit. This could be done directly over the network if the BSC service is exposed, or indirectly if the attacker can lure a user on the same network into visiting a malicious website. The vulnerability allows an attacker to write arbitrary data to any file on the system that the `ait-bsc` process has permission to access.
- Network access or local network compromise required.
- Unauthenticated HTTP API for packet capture.
- Arbitrary file write and potential denial of service.
Live Threat
Current exploitation, exposure, and threat context
The Binary Stream Capture component of the AMMOS Instrument Toolkit, when deployed with a publicly accessible network port or exploited through a compromised local website, could allow a remote attacker to append arbitrary data to any file on the system, using the privileges of the `ait-bsc` process. This could impact system integrity and potentially sensitive log files.
- Arbitrary file append on server.
- Path traversal via HTTP API.
- System integrity and log file compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
The AMMOS Instrument Toolkit's Binary Stream Capture component is susceptible to path traversal and arbitrary file append vulnerabilities. This impacts operations that utilize this component, potentially allowing remote attackers to compromise system integrity and availability. Ownership likely falls to the teams managing the specific instrument missions or ground data systems leveraging this toolkit, requiring an immediate inventory of affected systems, confirmation of network exposure and business criticality, and engagement with the accountable application or platform owners to plan remediation.
- Identify and own affected systems.
- Verify BSC accessibility and criticality.
- Plan and coordinate remediation actions.
