This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of NetGain Systems Enterprise Manager v7.2.699 build 1001. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the content parameter provided to the script_test.jsp endpoint. A crafted content request parameter can trigger execution of a system call composed from a user-supplied string. An attacker can leverage this vulnerability to execute code under the context of the web service. Was ZDI-CAN-5080.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
