PunBB Automatic Image Upload with Thumbnails module uploadimg.php file upload
| punbb-uploadimg-file-upload (39150) |  Medium Risk |
Description:
The PunBB Automatic Image Upload with Thumbnails module could allow a remote attacker to upload arbitrary files, caused by improper validation of file extensions by the uploadimg.php script. By sending a specially-crafted HTTP request with a forged MIME type header, a remote attacker could upload a malicious file, which could allow the attacker to execute arbitrary code on the vulnerable system or inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed, in order to steal the victim's cookie-based authentication credentials.
