What is CVE-2014-125119?

A filename spoofing vulnerability exists in WinRAR, where inconsistencies between the Central Directory and Local File Header in ZIP archives can be exploited. When users open specially crafted ZIP files, the file names displayed can differ from the actual files being extracted. This discrepancy allows attackers to masquerade malicious files as harmless ones, significantly increasing the risk of remote code execution when users unwittingly run the spoofed files.

Affected Version(s)

WinRAR 3.80 < 3.91

WinRAR 4.11 < 5.00

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.
