What is CVE-2025-70330?

Easy Grade Pro 4.1.0.2 exhibits a flaw in its file parsing logic, particularly when handling proprietary .EGP gradebook files. An attacker can exploit this vulnerability by crafting a specific .EGP file with altered fields at designated offsets. When the compromised file is processed by the application, it can lead to an out-of-bounds memory read, resulting in an unhandled access violation. This can cause the application to crash and create a local denial-of-service condition, preventing legitimate users from accessing their gradebooks.

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.
