https://notcve.org/view.php?id=CVE-2021-20110
Due to Manage Engine Asset Explorer Agent 1.0.34 not validating HTTPS certificates, an attacker on the network can statically configure their IP address to match the Asset Explorer's Server IP address. This will allow an attacker to send a NEWSCAN request to a listening agent on the network as well as receive the agent's HTTP request verifying its authtoken. In httphandler.cpp, the agent reaching out over HTTP is vulnerable to an Integer Overflow, which can be turned into a Heap Overflow allowing for remote code execution as NT AUTHORITY/SYSTEM on the agent machine. The Integer Overflow occurs when receiving POST response from the Manage Engine server, and the agent calling "HttpQueryInfoW" in order to get the "Content-Length" size from the incoming POST request. This size is taken, but multiplied to a larger amount. • https://www.tenable.com/security/research/tra-2021-31 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2021-20108
Manage Engine Asset Explorer Agent 1.0.34 listens on port 9000 for incoming commands over HTTPS from Manage Engine Server. The HTTPS certificates are not verified which allows any arbitrary user on the network to send commands over port 9000. While these commands may not be executed (due to authtoken validation), the Asset Explorer agent will reach out to the manage engine server for an HTTP request. During this process, AEAgent.cpp allocates 0x66 bytes using "malloc". This memory is never free-ed in the program, causing a memory leak. • https://www.tenable.com/security/research/tra-2021-29 • CWE-401: Missing Release of Memory after Effective Lifetime •

Due to the Asset Explorer agent not validating HTTPS certificates, an attacker on the network can statically configure their IP address to match the Asset Explorer's Server IP address. This will allow an attacker to send a NEWSCAN request to a listening agent on the network as well as receive the agent's HTTP request verifying its authtoken. In AEAgent.cpp, the agent responding back over HTTP is vulnerable to a Heap Overflow if the POST payload response is too large. The POST payload response is converted to Unicode using vswprintf. This is written to a buffer only 0x2000 bytes big. • https://www.tenable.com/security/research/tra-2021-30 • CWE-787: Out-of-bounds Write •
CVSS: 7.2EPSS: 7%CPEs: 1EXPL: 2CVE-2019-19034 – ManageEngine AssetExplorer Authenticated Command Execution
https://notcve.org/view.php?id=CVE-2019-19034
Zoho ManageEngine Asset Explorer 6.5 does not validate the System Center Configuration Manager (SCCM) database username when dynamically generating a command to schedule scans for SCCM. This allows an attacker to execute arbitrary commands on the AssetExplorer Server with NT AUTHORITY/SYSTEM privileges. Zoho ManageEngine Asset Explorer versión 6.5, no comprueba el nombre de usuario de la base de datos de System Center Configuration Manager (SCCM) cuando genera dinámicamente un comando para programar escaneos para SCCM. Esto permite a un atacante ejecutar comandos arbitrarios en el servidor AssetExplorer con privilegios NT AUTHORITY/SYSTEM. ManageEngine AssetExplorer versions prior to 6.5 (6503) suffer from an authenticated remote command execution vulnerability. • http://packetstormsecurity.com/files/157731/ManageEngine-AssetExplorer-Authenticated-Command-Execution.html http://seclists.org/fulldisclosure/2020/May/36 https://www.manageengine.com/products/asset-explorer/sp-readme.html • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.4EPSS: 0%CPEs: 1EXPL: 2CVE-2020-8838 – ManageEngine Asset Explorer Windows Agent Remote Code Execution
https://notcve.org/view.php?id=CVE-2020-8838
An issue was discovered in Zoho ManageEngine AssetExplorer 6.5. During an upgrade of the Windows agent, it does not validate the source and binary downloaded. This allows an attacker on an adjacent network to execute code with NT AUTHORITY/SYSTEM privileges on the agent machines by providing an arbitrary executable via a man-in-the-middle attack. Se detectó un problema en Zoho ManageEngine AssetExplorer versión 6.5. Durante una actualización del agente de Windows, no comprueba la fuente y el binario descargado. • http://packetstormsecurity.com/files/157612/ManageEngine-Asset-Explorer-Windows-Agent-Remote-Code-Execution.html http://seclists.org/fulldisclosure/2020/May/29 https://www.manageengine.com/products/asset-explorer/sp-readme.html • CWE-354: Improper Validation of Integrity Check Value •
