Multiple Zoho ManageEngine on-premise products, such as ServiceDesk Plus through 14003, allow remote code execution due to use of Apache Santuario xmlsec (aka XML Security for Java) 1.4.1, because the xmlsec XSLT features, by design in that version, make the application responsible for certain security protections, and the ManageEngine applications did not provide those protections. This affects Access Manager Plus before 4308, Active Directory 360 before 4310, ADAudit Plus before 7081, ADManager Plus before 7162, ADSelfService Plus before 6211, Analytics Plus before 5150, Application Control Plus before 10.1.2220.18, Asset Explorer before 6983, Browser Security Plus before 11.1.2238.6, Device Control Plus before 10.1.2220.18, Endpoint Central before 10.1.2228.11, Endpoint Central MSP before 10.1.2228.11, Endpoint DLP before 10.1.2137.6, Key Manager Plus before 6401, OS Deployer before 1.1.2243.1, PAM 360 before 5713, Password Manager Pro before 12124, Patch Manager Plus before 10.1.2220.18, Remote Access Plus before 10.1.2228.11, Remote Monitoring and Management (RMM) before 10.1.41. ServiceDesk Plus before 14004, ServiceDesk Plus MSP before 13001, SupportCenter Plus before 11026, and Vulnerability Manager Plus before 10.1.2220.18. Exploitation is only possible if SAML SSO has ever been configured for a product (for some products, exploitation requires that SAML SSO is currently active).

Zoho Desktop Central contains an authentication bypass vulnerability that could allow an attacker to execute arbitrary code in the Desktop Central MSP server.

An XML external entity (XXE) vulnerability in Zoho ManageEngine Desktop Central before the 07-Mar-2020 update allows remote unauthenticated users to read arbitrary files or conduct server-side request forgery (SSRF) attacks via a crafted DTD in an XML request.

Zoho ManageEngine Desktop Central before 10.0.474 allows remote code execution because of deserialization of untrusted data in getChartImage in the FileStorage class. This is related to the CewolfServlet and MDMLogUploaderServlet servlets.

Unrestricted file upload vulnerability in AgentLogUploadServlet in ManageEngine DesktopCentral 7.x and 8.0.0 before build 80293 allows remote attackers to execute arbitrary code by uploading a file with a jsp extension, then accessing it via a direct request to the file in the webroot.

An issue was discovered in Zoho ManageEngine Desktop Central 10.0.124 and 10.0.184: directory traversal in the SCRIPTNAME field when modifying existing scripts.

An issue was discovered in Zoho ManageEngine Desktop Central 10.0.124 and 10.0.184: insufficient enforcement of database query type restrictions.

An issue was discovered in Zoho ManageEngine Desktop Central 10.0.124 and 10.0.184: a missing server-side check on the file type/extension when uploading and modifying scripts.

An issue was discovered in Zoho ManageEngine Desktop Central 10.0.124 and 10.0.184: missing authentication/authorization for a database query mechanism.

Remote Information Disclosure and Escalation of Privileges in ManageEngine Desktop Central MSP 10.0.137 allows attackers to download unencrypted XML files containing all data for configuration policies via a predictable /client-data/<clientid>/collections/##/usermgmt.xml URL, as demonstrated by passwords and Wi-Fi keys. This is fixed in build 100157.

Zoho ManageEngine Desktop Central before build 100092 allows remote attackers to execute arbitrary code via vectors involving the upload of help desk videos.
