CVE-2017-15643 – Ikraus Anti Virus 2.16.7 - Remote Code Execution

https://notcve.org/view.php?id=CVE-2017-15643

An active network attacker (MiTM) can achieve remote code execution on a machine that runs IKARUS Anti Virus 2.16.7. IKARUS AV for Windows uses cleartext HTTP for updates along with a CRC32 checksum and an update value for verification of the downloaded files. The attacker first forces the client to initiate an update transaction by modifying an update field within an HTTP 200 response, so that it refers to a nonexistent update. The attacker then modifies the HTTP 404 response so that it specifies a successfully found update, with a Trojan horse executable file (e.g., guardxup.exe) and the correct CRC32 checksum for that file. Un atacante de red activo (Man in the Middle o MiTM) puede conseguir la ejecución remota de código en una máquina que ejecute IKARUS Anti Virus, versión 2.16.7. • https://www.exploit-db.com/exploits/44055 https://blogs.securiteam.com/index.php/archives/3485 https://www.ikarussecurity.com/about-ikarus/security-blog/vulnerability-in-windows-antivirus-products-ik-sa-2017-0001 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
