Description:
Some vulnerabilities have been discovered in Barcode Generator, which can be exploited by malicious people to disclose sensitive information or compromise a vulnerable system.
1) Input passed to the "code" parameter in html/image.php (when "t", "r", "text", "f1", "f2", "o", "a1","a2" are set to non-null values) is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
2) Input passed to the "class_dir" in class/LSTable.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local and external resources.
Successful exploitation requires that "register_globals" is enabled.
This vulnerabilities are confirmed in Barcode Generator 1d 2.0.0. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified.
