Horizon Alert
Summary of the vulnerability and why it matters
This advisory details a critical operating system command injection vulnerability affecting AndSoft's e-TMS software, allowing unauthorized command execution on servers through a specific POST request. While the technical details involve exploiting a parameter in a login form, the high-level implication is potential server compromise via network access.
- Allows attackers to run commands on servers.
- Matters due to potential server compromise.
- Confirm relevance and impact within our environment.
Attack Path
How an attacker could exploit the issue
An attacker could target the e-TMS login page, exploiting a flaw in how it handles specific data. By sending a crafted POST request to the login form, an attacker might trick the server into executing arbitrary operating system commands, potentially leading to a compromise of the server.
- Requires unauthenticated network access.
- Triggered by sending a POST request.
- Risk of arbitrary command execution.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to execute arbitrary operating system commands on the affected server by sending a specially crafted POST request to the `/clt/LOGINFRM_BET.ASP` endpoint. The system data that could be affected is not specified, nor is user data or PII. The successful exploitation of this vulnerability could lead to unauthorized command execution on the server.
- Server operating system commands are at risk.
- Attacker sends a POST request to a specific endpoint.
- Unauthorized command execution on the server.
Operational Fix
Recommended remediation, mitigation, and detection steps
The operating system command injection vulnerability in e-TMS is likely the responsibility of the application owner and infrastructure teams, as it affects a web-based login component. The first practical step is to identify all instances of e-TMS, determine their internet exposure, and confirm business criticality. Once identified, the accountable owner must be located to plan remediation based on the assessed risk.
- Application and infrastructure teams own remediation.
- Verify internet accessibility and business criticality.
- Plan and execute risk-based remediation.
