HTTP Nonnoi ASP BarCode ActiveX File Overwrite

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.

Description

This signature detects attempt to exploit a file overwrite vulnerability by passing special arguments into a method of Nonnoi ASP/Barcode COM Component ActiveX control.

Additional Information

Nonnoi ASP/Barcode is a server-side COM component used to add barcodes to applications.

The ActiveX control is prone to a vulnerability that lets attackers overwrite arbitrary files on the victim's computer in the context of the vulnerable application using the ActiveX control (typically Internet Explorer). This issue occurs because the application fails to sanitize user-supplied input to the 'filenameA' parameter of the 'SaveBarcode()' in the 'nonnoi_ASPBarcode.dll' library.

An attacker can exploit this issue to overwrite arbitrary files on the victim's computer in the context of the vulnerable application using the ActiveX control (typically Internet Explorer).

This issue affects Nonnoi ASP/Barcode 2.20; other versions may also be affected.
