Luigi Auriemma has reported some vulnerabilities and a security issue in ASG-Sentry Network Manager, which can be exploited by malicious people to manipulate certain data, bypass certain security restrictions, cause a DoS (Denial of Service), or compromise a vulnerable system.

1) A vulnerability is caused due to the file check utility "fcheck.exe" overwriting arbitrary files specified via the "-b" option in an HTTP request.

2) A boundary error in the "FxAgent" process can be exploited to caused a heap-based buffer overflow by sending a specially crafted SNMP request containing an overly long community string.

3) Commands sent to the "FxIAList" service are not authenticated. This can be exploited to e.g. stop the service by sending an "exit" command to port 6162/TCP.

4) A boundary error in the "FxIAList" service can be exploited to cause a stack-based buffer overflow by sending a specially crafted packet to port 6162/TCP.

Successful exploitation of this vulnerability allows execution of arbitrary code.

The vulnerabilities are reported in version 7.0.0. Other versions may also be affected.

Solution
Restrict network access to the services.
