CVE-2025-51726 NOMISEC HIGH WRITEUP
CyberGhostVPNSetup.exe - Cryptographic Hash Collision
CyberGhostVPNSetup.exe (Windows installer) is signed using the weak cryptographic hash algorithm SHA-1, which is vulnerable to collision attacks. This allows a malicious actor to craft a fake installer with a forged SHA-1 certificate that may still be accepted by Windows signature verification mechanisms, particularly on systems without strict SmartScreen or trust policy enforcement. Additionally, the installer lacks High Entropy Address Space Layout Randomization (ASLR), as confirmed by BinSkim (BA2015 rule) and repeated WinDbg analysis. The binary consistently loads into predictable memory ranges, increasing the success rate of memory corruption exploits. These two misconfigurations, when combined, significantly lower the bar for successful supply-chain style attacks or privilege escalation through fake installers.
CVSS 8.4
CVE-2025-57392 NOMISEC HIGH WORKING POC
BenimPOS Masaustu 3.0.x - Insecure File Permissions
BenimPOS Masaustu 3.0.x is affected by insecure file permissions. The application installation directory grants Everyone and BUILTIN\Users groups FILE_ALL_ACCESS, allowing local users to replace or modify .exe and .dll files. This may lead to privilege escalation or arbitrary code execution upon launch by another user or elevated context.
CVSS 7.8
