Description: 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.
The vulnerability is reported in version 1.0k. Other versions may also be affected.
Solution: Restrict outbound network connections to "lsyn.webhop.net" and attempts to send e-mails to "defcola@gmail.com".
