What is CVE-2018-5282?

Kentico Web Content Management System versions 9.0 to 11.0 are vulnerable to a stack-based buffer overflow due to improper handling of input from the SqlName, SqlPswd, Database, UserName, or Password fields in a SilentInstall XML document. This flaw may allow an attacker to exploit the system, potentially leading to unauthorized access or other malicious actions. However, the vendor has contested the issue, stating that they could not reproduce a buffer overflow or system crash, emphasizing that XML document processing occurs entirely within the managed code of the Microsoft .NET Framework.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
