Zoho Corp ManageEngine ADSelfService Plus

Zoho ManageEngine ADSelfService Plus through 6102 allows unauthenticated remote code execution in non-English editions.

An issue was discovered in Zoho ManageEngine Exchange Reporter Plus before build number 5510, AD360 before build number 4228, ADSelfService Plus before build number 5817, DataSecurity Plus before build number 6033, RecoverManager Plus before build number 6017, EventLog Analyzer before build number 12136, ADAudit Plus before build number 6052, O365 Manager Plus before build number 4334, Cloud Security Plus before build number 4110, ADManager Plus before build number 7055, and Log360 before build number 5166. The remotely accessible Java servlet com.manageengine.ads.fw.servlet.UpdateProductDetails is prone to an authentication bypass. System integration properties can be modified and lead to full ManageEngine suite compromise.

An elevation of privilege vulnerability exists in ManageEngine ADSelfService Plus before build 6003 because it does not properly enforce user privileges associated with a Certificate dialog. This vulnerability could allow an unauthenticated attacker to escalate privileges on a Windows host. An attacker does not require any privilege on the target system in order to exploit this vulnerability. One option is the self-service option on the Windows login screen. Upon selecting this option, the thick-client software is launched, which connects to a remote ADSelfService Plus server to facilitate self-service operations. An unauthenticated attacker having physical access to the host could trigger a security alert by supplying a self-signed SSL certificate to the client. The View Certificate option from the security alert allows an attacker to export a displayed certificate to a file. This can further cascade to a dialog that can open Explorer as SYSTEM. By navigating from Explorer to \windows\system32, cmd.exe can be launched as a SYSTEM.

Zoho ManageEngine ADSelfService Plus 5.x before build 5703 has SSRF.

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

Zoho ManageEngine ADSelfService Plus through 6101 is vulnerable to unauthenticated Remote Code Execution while changing the password.

Zoho ManageEngine ADSelfService Plus before 5815 allows unauthenticated remote code execution.

The custom GINA/CP module in Zoho ManageEngine ADSelfService Plus before 5.5 build 5517 allows remote attackers to execute code and escalate privileges via spoofing. It does not authenticate the intended server before opening a browser window. An unauthenticated attacker capable of conducting a spoofing attack can redirect the browser to gain execution in the context of the WinLogon.exe process. If Network Level Authentication is not enforced, the vulnerability can be exploited via RDP. Additionally, if the web server has a misconfigured certificate then no spoofing attack is required

Zoho ManageEngine ADSelfService Plus 5.x before build 5701 has XXE via an uploaded product license.

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 version 6103 and prior allows CAPTCHA bypass due to improper parameter validation.

Zoho ManageEngine ADSelfService Plus 6111 and prior is vulnerable to SQL Injection while linking the databases.

Zoho ManageEngine ADSelfService Plus 6111 and prior is vulnerable to linked applications takeover.

Zoho ManageEngine ADSelfService Plus 6103 and prior is vulnerable to admin portal access-restriction bypass.

A CSV injection vulnerability on the login panel of ManageEngine ADSelfService Plus Version: 6.1 Build No: 6101 can be exploited by an unauthenticated user. The j_username parameter seems to be vulnerable and a reverse shell could be obtained if a privileged user exports "User Attempts Audit Report" as CSV file. Note: The vendor disputes this vulnerability, claiming "This is not a valid vulnerability in our ADSSP product. We don't see this as a security issue at our side.

An issue was discovered in Zoho ManageEngine ADSelfService Plus 5.6 Build 5607. An exposed service allows an unauthenticated person to retrieve internal information from the system and modify the product installation.

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

Authentication Bypass

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.

Remote code execution

Zoho ManageEngine ADSelfService Plus 5.x through 5803 has CSRF on the users' profile information page. Users who are attacked with this vulnerability will be forced to modify their enrolled information, such as email and mobile phone, unintentionally. Attackers could use the reset password function and control the system to send the authentication code back to the channel that the attackers own.

Zoho ManageEngine ADManager Plus 6.6.5, ADSelfService Plus 5.7, and DesktopCentral 10.0.380 have Insecure Permissions, leading to Privilege Escalation from low level privileges to System.

SQL Injection

Account takeover

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

An issue was discovered in Zoho ManageEngine ADSelfService Plus 5.x through build 5704. It uses fixed ciphering keys to protect information, giving the capacity for an attacker to decipher any protected data.

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

An authentication bypass vulnerability in the password reset functionality in Zoho ManageEngine ADSelfService Plus before 5.0.6 allows an attacker with physical access to gain a shell with SYSTEM privileges via the restricted thick client browser. The attack uses a long sequence of crafted keyboard input.

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.
