CVE-2024-13990 (GCVE-0-2024-13990)
Vulnerability from cvelistv5 – Published: 2025-09-19 18:54 – Updated: 2025-11-19 15:58 X_Known Exploited Vulnerability

Title
MicroWorld eScan AV Insecure Update Mechanism Allows Man-in-the-Middle Replacement of Updates
Summary
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.
