Due to missing encoding in SAP Contact Center's Communication Desktop component- version 700, an attacker could send malicious script in chat message.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Due to missing encoding in SAP Contact Center's Communication Desktop component- version 700, an attacker could send malicious script in chat message. When the message is accepted by the chat recipient, the script gets executed in their scope. Due to the usage of ActiveX in the application, the attacker can further execute operating system level commands in the chat recipient's scope. This could lead to a complete compromise of their confidentiality, integrity, and could temporarily impact their availability.
