Descriptions

The client implementation in IBM Informix Dynamic Server 11.70.xCn on Windows does not properly restrict access to the (1) nsrd, (2) nsrexecd, and (3) portmap executable files, which allows local users to gain privileges via a Trojan horse file.

La implementación del cliente en IBM Informix Dynamic Server 11.70.xCn en Windows no restringe adecuadamente el acceso a los archivos ejecutables (1) nsrd, (2) nsrexecd y (3) portmap, lo que permite a usuarios locales obtener privilegios a través de un archivo troyano.

This vulnerability allows local users to execute arbitrary code on vulnerable installations of IBM Informix. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within configuration of the portmap service. Weak access control allows all authenticated users to modify the binary for this service and thus execute code in the context of SYSTEM.
