Published Oct 19, 2017 ikarussecurity CWE-444

Overview

CVE-2017-15643 is a high-severity vulnerability affecting ikarussecurity ikarus_antivirus. It was published on October 19, 2017 and has a CVSS 3.0 base score of 7.4 (HIGH).

This vulnerability has a CVSS 3.0 base score of 7.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories and patches from ikarussecurity. Update ikarus_antivirus to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
