Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the SOCFortress CoPilot platform could allow an attacker to overwrite application files, potentially disrupting operations. This issue stems from how the platform handles uploaded report filenames, allowing for directory traversal and unintended file modifications. While the demonstrated impact does not involve unrestricted code execution or data breaches across tenants, the ability to alter application files poses a risk to service stability.
- A flaw lets attackers write files outside the intended location.
- Critical vulnerability in security operations reporting tool.
- Confirm relevance and exposure; assess impact on operations.
Attack Path
How an attacker could exploit the issue
An attacker can target the SOCFortress CoPilot application by exploiting a vulnerability in how it handles uploaded report filenames. This vulnerability allows an attacker to write files to arbitrary locations on the host system. The attacker starts by interacting with the application's API, specifically the `POST /api/scoutsuite/generate-gcp-report` endpoint. By crafting a malicious filename within the uploaded content, the attacker can cause the application to write files outside of its intended directory, potentially overwriting critical application files and disrupting its operation.
- Unauthenticated network access required.
- Maliciously named uploaded file.
- Overwrite application files, disrupt operations.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, this vulnerability could allow an attacker to overwrite arbitrary files on the host system. This is possible when an admin or analyst user uploads a specially crafted JSON file, which can then be written outside its intended directory due to improper filename sanitization. The impact is limited to file overwrites within the application's source directory and can disrupt application operation, but does not lead to unrestricted code execution or direct cross-tenant data loss.
- Application source files could be overwritten.
- Malicious filename in uploaded JSON content.
- Disruption of application service availability.
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability impacts the SOCFortress CoPilot application, specifically its handling of user-uploaded content. The platform team or application owners are likely responsible for addressing this, as it involves code within the application's backend. The first practical step is to identify all instances of the affected technology, confirm if the vulnerable API endpoint is externally reachable or handles business-critical data, and then determine the accountable owner for remediation planning.
- Application or platform teams own the fix.
- Verify external reachability of the API.
- Plan remediation based on exposure and criticality.
