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

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 before 6202 allows attackers to perform username enumeration via a crafted POST request to /ServletAPI/accounts/login.

Zoho ManageEngine ADSelfService Plus before 6121, ADAuditPlus 7060, Exchange Reporter Plus 5701, and ADManagerPlus 7131 allow NTLM Hash disclosure during certain storage-path configuration steps.

Zoho ManageEngine ADSelfService Plus before build 6122 allows a remote authenticated administrator to execute arbitrary operating OS commands as SYSTEM via the policy custom script feature. Due to the use of a default administrator password, attackers may be able to abuse this functionality with minimal effort. Additionally, a remote and partially authenticated attacker may be able to inject arbitrary commands into the custom script due to an unsanitized password field.

Zoho ManageEngine ADSelfService Plus before 6121 allows XSS via the welcome name attribute to the Reset Password, Unlock Account, or User Must Change Password screen.

ManageEngine ADSelfService Plus below build 6116 stores the password policy file for each domain under the html/ web root with a predictable filename based on the domain name. When ADSSP is configured with multiple Windows domains, a user from one domain can obtain the password policy for another domain by authenticating to the service and then sending a request specifying the password policy file of the other domain.
