codeblocks

Code Blocks 20.03 contains a denial of service vulnerability that allows attackers to crash the application by manipulating input in the FSymbols search field. Attackers can paste a large payload of 5000 repeated characters into the search field to trigger an application crash.

CODE::BLOCKS 16.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler with crafted Unicode characters. Attackers can create a malicious M3U playlist file with 536 bytes of buffer and shellcode to trigger remote code execution.

The Coding Blocks plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.0. This is due to missing nonce validation on the settings update functionality. This makes it possible for unauthenticated attackers to update plugin settings including the theme configuration via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
