CVE-2018-25169
7.5AMPPS · AMPPS
AMPPS 2.7 is vulnerable to a denial of service attack where unauthenticated remote attackers can crash the service by sending malformed data to the default HTTP port.
Executive summary
A critical denial of service vulnerability in AMPPS 2.7 allows unauthenticated attackers to crash the application by exhausting system resources through malformed network traffic.
Vulnerability
The application is vulnerable to a resource exhaustion attack due to insecure handling of socket connections. An unauthenticated remote attacker can send multiple malformed payloads to the default HTTP port, causing the service to crash and resulting in a denial of service.
Business impact
Successful exploitation of this vulnerability results in service unavailability, preventing legitimate users from accessing hosted applications or services. Given the CVSS score of 7.5, this high severity flaw poses a significant risk to business continuity, as it allows any unauthenticated attacker to disrupt critical operations without requiring specialized knowledge or credentials.
Remediation
Immediate Action: Upgrade to the latest version of AMPPS to receive the necessary security patches addressing this resource management flaw.
Proactive Monitoring: Monitor server logs and resource utilization metrics for frequent, unauthorized socket connection attempts or sudden spikes in memory and CPU usage that correlate with service interruptions.
Compensating Controls: Implement rate limiting and connection filtering on the firewall or a Web Application Firewall (WAF) to restrict the number of concurrent connections from single IP addresses, which can help mitigate the impact of this denial of service vector.
Exploitation status
Public Exploit Available: Yes, a proof of concept exists, as documented on Exploit Database (EDB-ID 45850).
Analyst recommendation
The vulnerability in AMPPS 2.7 represents a direct threat to service availability that can be easily triggered by remote, unauthenticated actors. Administrators should prioritize updating the software to a patched version immediately to prevent potential service disruption. If an update is not immediately feasible, network-level controls must be applied to limit the exposure of the management interface.
