Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability has been identified in Termix, a web-based server management platform, allowing authenticated users with active file management sessions to execute arbitrary commands on connected remote hosts. This issue arises from inadequate escaping of shell commands within a specific endpoint, potentially enabling unauthorized access and control over server operations. The main concern is confirming relevance and exposure of this platform within your environment.
- Unauthenticated users can run any command on servers.
- It affects remote server access and management tools.
- Confirm if your organization uses this management software.
Attack Path
How an attacker could exploit the issue
An attacker with authenticated access to Termix and an active File Manager SSH session could exploit a vulnerability in the `resolvePath` endpoint. By manipulating the input to this endpoint, an attacker can inject operating system commands that are then executed on the remote host connected via SSH. This can allow an attacker to gain control over the remote system.
- Authenticated user with active session.
- Insecure path resolution endpoint.
- Arbitrary command execution on host.
Live Threat
Current exploitation, exposure, and threat context
An authenticated user with an active File Manager SSH session in Termix could execute arbitrary commands on the connected remote host when the affected versions are used and the specific endpoint is accessed. This could impact the confidentiality, integrity, and availability of the remote host.
- Remote host commands could be executed.
- Vulnerability exploits unpatched command substitution.
- Complete compromise of the remote host.
Operational Fix
Recommended remediation, mitigation, and detection steps
System owners are likely responsible for managing Termix, a web-based server management platform. The initial focus should be on identifying all instances of Termix, assessing their exposure and business criticality, and then locating the accountable owner to plan remediation.
- Identify Termix instances and owners.
- Verify Termix reachability and criticality.
- Plan remediation based on risk.
