A recent critical vulnerability, CVE-2023-21582, has been discovered in Adobe's popular e-reader and eBook management software, Adobe Digital Editions. This vulnerability exists specifically in version 184.108.40.206303 and earlier versions. The consequences of this vulnerability being exploited successfully can lead to an out-of-bounds write, which in turn, could result in arbitrary code execution.
In order for an attacker to exploit this vulnerability, they need to deceive the victim into opening a malicious file using the affected version of Adobe Digital Editions. The vulnerability can then be triggered, leading to an out-of-bounds write and arbitrary code execution in the context of the current user.
Unfortunately, we cannot provide specific exploit code due to ethical reasons, but it's important to understand that the malicious file will likely be crafted in such a way that it triggers a memory corruption in the software, allowing the attacker to write outside the boundaries of a buffer. This can then be manipulated to execute arbitrary code.
