Description:
Some vulnerabilities have been reported in LightBlog, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or compromise a vulnerable system.
1) Input passed to the "username_post" parameter in login.php (when "password_post" is set) and the "Lightblog_username" cookie in check_user.php (when the "Lightblog_password" cookie is set) is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
The vulnerabilities are confirmed in version 9.8. Other versions may also be affected.
2) Input passed via parameters (e.g. "email_post") to register.php is not properly sanitised before being stored within a php file. This can be exploited to inject and execute arbitrary PHP code.
3) Input passed via the "Lightblog_username" cookie in check_user.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.
NOTE: This can further be exploited to gain access to the application by providing a specially crafted "Lightblog_username" cookie and to upload and execute arbitrary PHP code.
Vulnerabilities #2 and #3 are reported in version 9.9.2. Other versions may also be affected.
