Where	From remote "From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network. This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
Impact	System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.
Description	A security issue has been discovered in odlican.net CMS, which can be exploited by malicious people to compromise a vulnerable system. The security issue is caused due to missing access restrictions to the upload.php script. This can be exploited to upload arbitrary files to the "files" folder inside the webroot and e.g. execute arbitrary PHP code. The security issue is confirmed in version 1.5. Other versions may also be affected.
Solution	Reportedly fixed in version 1.6.
