Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-40779 is an open redirection issue, tracked under CWE-601, that affects IceWarp Mail Server Deep Castle 2 version 13.0.1.2. The vulnerability resides in the web client component and permits a remote attacker to supply a crafted request to a URL that triggers the flaw, resulting in a CVSS 6.1 rating driven by network attack vector, low complexity, and required user interaction.

An unauthenticated remote attacker can exploit the weakness by sending a maliciously formed URL to a victim user. Successful exploitation allows the attacker to redirect the user to an arbitrary destination under attacker control, which can be leveraged to facilitate phishing or further client-side attacks that ultimately lead to arbitrary code execution within the affected session.

Public references describe the flaw as an open redirection vulnerability in the IceWarp Webclient product and provide technical details on the request manipulation required for exploitation. No vendor advisory or patch information is included in the supplied references.

The EPSS score for this CVE has remained flat at its peak value of 0.4052 since disclosure, indicating no material increase in observed exploitation interest.
