IKARUS Anti Virus 2.16.7 - Remote Code Execution via HTTP Update Response Manipulation

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2017-15643. PoCs published by SecuriTeam.

AI-analyzed exploit summary This exploit leverages a man-in-the-middle (MiTM) attack to intercept and modify HTTP update requests from Ikarus Anti Virus, allowing an attacker to replace the legitimate update executable with a malicious one. The PoC uses mitmproxy to manipulate the update version number and inject a custom executable, achieving remote code execution.

Description

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.
