Insecure method was founded in NCSECWLib ActiveX control component which is a part of Oracle Document Capture. One of the methods (WriteJPG) can be used to owervrite files on users system and also affected to buffer overflow.
An attacker can send a malicious link to an unaware user via an e-mail, messaging or social networks. He also can insert this link into corporate portal. When clicking this link the end user browser will call vulnerable ActiveX component which can delete any file on victim’s workstation. It is possible to delete configuration files of critical binaries that can lead to denial of service attack and stopping business until files will be repaired. This scenario is critical if user works with SAP for Logistics or SAP for Banking applications.
