Horizon Alert
Summary of the vulnerability and why it matters
This advisory details a critical operating system command injection vulnerability identified in AndSoft's e-TMS software. The flaw allows an unauthenticated attacker to execute commands on the server through a specially crafted POST request targeting the login form. This could potentially lead to a compromise of the affected server.
- Attackers can run commands on vulnerable servers.
- This affects our transport management system's login.
- Confirm relevance and exposure of the system.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending a specially crafted POST request to the `/clt/LOGINFRM_LXA.ASP` endpoint. This request targets a specific parameter within the login form, allowing the attacker to inject operating system commands that will be executed on the server. The system could then perform actions dictated by the attacker.
- No authentication or special access required.
- Sending a POST request to the login endpoint.
- Arbitrary operating system command execution on server.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to execute arbitrary operating system commands on the server when they send a specially crafted POST request to a specific login endpoint. The commands would run with the privileges of the web server process.
- System commands could be executed remotely.
- Via a POST request to a login endpoint.
- Unauthorized command execution on the server.
Operational Fix
Recommended remediation, mitigation, and detection steps
Application owners and infrastructure teams are likely responsible for addressing this operating system command injection vulnerability in e-TMS, as it affects a server-side component accessible via a POST request. The first practical step is to identify all instances of e-TMS, confirm their exposure and criticality, and then engage the accountable owner to plan remediation based on the assessed risk.
- Application and infrastructure teams own this.
- Verify e-TMS instances and exposure first.
- Plan remediation based on risk.
