Title: Leif M. Wright Web Blog Remote Command Execution Vulnerability
Severity: HIGH
Description:
Web Blog is a web application, written by Leif M. Wright.
Web Blog has been reported to be prone to a vulnerability that may permit remote attackers to execute arbitrary commands in the context of the hosting web server. This is due to insufficient sanitization of shell metacharacters from variables which will be used as an argument to a function that invokes the shell directly.
This issue exists in the blog.cgi script and is exposed via the 'file' URI parameter when submitting a 'ViewFile' request to the script. Exploitation could permit a remote attacker to gain interactive access to the underlying operating system of the host.
Affected Products:
- Leif M. Wright Web Blog 1.1.0
- Leif M. Wright Web Blog 1.1.5
