Title: Chili!Soft License File Deletion DOS Vulnerability

Severity: LOW

Description:

ChiliSoft ASP (CASP) is a cross-platform Active Server Pages implementation for Linux and other platforms including Lotus Domino, Apache, HP-UX, AIX and others.

Chilisoft ASP's web-based license update tool creates its server license file as world-writeable. As a result, any local user may overwrite, delete or modify it.

Because the program will fail to run if the license file is absent or rendered invalid, deletion of this file by a local user has the effect of a denial of service attack on the webserver's ASP support.

Common on web hosting systems where multiple users from different organizations having access to the same systems. A malicious user in any of these organizations may be able to create a DoS for all users sharing the system.

Affected Products:

  • Chilisoft ChiliSoft ASP for Linux 3.0.0
  • Chilisoft ChiliSoft ASP for Linux 3.5.0
  • Chilisoft ChiliSoft ASP for Linux 3.5.2
