Zoho ManageEngine ADSelfService Plus version 6113 and prior is vulnerable to REST API authentication bypass with resultant remote code execution.

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 10.1.2…

Zoho ManageEngine ADSelfService Plus versions below 6401 are vulnerable to the DOS attack due to the malicious LDAP input.

ManageEngine ADSelfService Plus versions 6401 and below are vulnerable to the remote code execution due to the improper handling in the load balancer component. Authentication is required in order to exploit this vulnerability.

An information disclosure vulnerability exists in multiple ManageEngine products that can result in encryption keys being exposed. A low-privileged OS user with access to the host where an affected ManageEngine product is installed can view and use the exposed key to decrypt product database passwords. This allows the user to access the ManageEngine product database.

ManageEngine ADSelfService Plus GINA Client Insufficient Verification of Data Authenticity Authentication Bypass Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of ManageEngine ADSelfService Plus. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Password Reset Portal used by the GINA client. The issue results from the lack of proper authentication of data received via HTTP. An attacker can leverage this vulnerability to bypass authentication and execute code in the context of SYSTEM. Was ZDI-CAN-17009.

Zoho ManageEngine ADSelfService Plus through 6113 has an authentication bypass that can be exploited to steal the domain controller session token for identity spoofing, thereby achieving the privileges of the domain controller administrator. NOTE: the vendor's perspective is that they have "found no evidence or detail of a security vulnerability."

Zoho ManageEngine ADSelfService Plus before 6218 allows anyone to conduct a Denial-of-Service attack via the Mobile App Authentication API.

Zoho ManageEngine ADSelfService Plus through 6203 is vulnerable to a brute-force attack that leads to a password reset on IDM applications.

Zoho ManageEngine ADSelfService Plus before 6203 allows a denial of service (application restart) via a crafted payload to the Mobile App Deployment API.
