Title: Sun Sunsolve CD SSCD_SunCourier.pl CGI Script Arbitrary Command Execution Vulnerability

Severity: HIGH

Description:

The Sunsolve CD is part of the Solaris Media pack. It is included as a documentation resource, and is available for the Solaris Operating Environment.

A problem with the sscd_suncourier.pl script included with the package could make it possible for a remote user to execute arbitrary commands on a vulnerable system.

The Sunsolve CD is not installed as part of the default installation of the operating system. It is instead included as an add-on CD with documentation, and a web browser that runs with lowered permissions when the program is run.

A CGI script included with the CD does not adequately sanitize input. Due to a design failure which does not remove special characters such as the pipe (|) character, a user submitting a malicious email address to the script could execute arbitrary commands with the permissions of the executing program.

Affected Products:

  • Sun Solaris 7.0
  • Sun Solaris 7.0_x86
  • Sun Solaris 8
  • Sun Solaris 8_x86
