CVE-2024-13990 Detail

Description

MicroWorld eScan AV's update mechanism failed to ensure authenticity and integrity of updates: update packages were delivered and accepted without robust cryptographic verification. As a result, an on-path attacker could perform a man-in-the-middle (MitM) attack and substitute malicious update payloads for legitimate ones. The eScan AV client accepted these substituted packages and executed or loaded their components (including sideloaded DLLs and Java/installer payloads), enabling remote code execution on affected systems. MicroWorld eScan confirmed remediation of the update mechanism on 2023-07-31 but versioning details are unavailable. NOTE: MicroWorld eScan disputes the characterization in third-party reports, stating the issue relates to 2018–2019 and that controls were implemented then.
