AN independent researcher known as Nightmare Eclipse has unveiled an experimental exploit called HardBreacher, targeting Kaspersky Endpoint Security. This exploit exposes a zero-day vulnerability, allowing unprivileged users to bypass Windows privilege boundaries and create files in the System32 directory. Although the exploit has been tested on Kaspersky version 14.0.0.504, it currently operates with instability and is not yet reliable for consistent execution.
The underlying issue relates to how Kaspersky’s interface process interacts with the operating system, potentially leading to severe security implications. The exploit remains unconfirmed, lacking a CVE identifier and successful reproduction by third-party researchers, emphasizing the need for further verification in the realm of endpoint security.
