The MicroWorld Agent service (MWAGENT.EXE) in MicroWorld Technologies eScan 8.0.671.1, and possibly other versions, allows remote or local attackers to gain privileges and execute arbitrary commands by connecting directly to TCP port 2222.

Stack-based buffer overflow in the MicroWorld Agent service (MWAGENT.EXE) in MicroWorld Technologies eScan before 9.0.718.1 allows remote attackers to execute arbitrary code via a long command.

MicroWorld eScan Virus Control 9.0.722.1, Anti-Virus 9.0.722.1, and Internet Security 9.0.722.1 use weak permissions (Everyone:Full Control) for their installation directory trees, which allows local users to gain privileges by replacing application files, as demonstrated by traysser.exe.

Absolute path traversal vulnerability in the FTP server in MicroWorld eScan Corporate Edition 9.0.742.98 and eScan Management Console (aka eScan Server) 9.0.742.1 allows remote attackers to read arbitrary files via an absolute pathname in the RETR (get) command.

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

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.

A kernel handle leak issue in ProcObsrvesx.sys 4.0.0.49 in MicroWorld Technologies Inc eScan Antivirus could allow privilege escalation for low-privileged users.
