Chris has reported a vulnerability in the Cypress script for
BitchX, which can be exploited by malicious people to disclose
potentially sensitive information or to compromise a vulnerable
system.
The vulnerability is caused due to malicious code being present
in the modules/mdop.m file. This can be exploited to disclose the
content of various system files or to execute arbitrary shell
commands.
Successful exploitation allows execution of arbitrary code, but
requires the control of the "lsyn.webhop.net" domain.
