It is reported that cURL allows malicious users to bypass 'open_basedir' restrictions in PHP scripts. This issue is due to a failure of the cURL module to properly enforce PHPs 'open_basedir' restriction.
Users with the ability to create or modify PHP scripts on a server computer hosting the vulnerable software can reportedly exploit this vulnerability to bypass the 'open_basedir' restriction, and access arbitrary files with the privileges of the web server. This may aid them in further attacks.
This vulnerability possibly results in a false sense of security, as administrators expect that the restrictions in place prevent malicious users from gaining access to sensitive information.
