Zohocorp : Security Vulnerabilities, CVEs,

Directory traversal vulnerability in the agentLogUploader servlet in ZOHO ManageEngine Desktop Central (DC) and Desktop Central Managed Service Providers (MSP) edition before 9 build 90055 allows remote attackers to write to and execute arbitrary files as SYSTEM via a .. (dot dot) in the filename parameter.

The NativeAppServlet in ManageEngine Desktop Central MSP before 90075 allows remote attackers to execute arbitrary code via a crafted JSON object.

ManageEngine Applications Manager 12 and 13 before build 13200, allows unserialization of unsafe Java objects. The vulnerability can be exploited by remote user without authentication and it allows to execute remote code compromising the application as well as the operating system. As Application Manager's RMI registry is running with privileges of system administrator, by exploiting this vulnerability an attacker gains highest privileges on the underlying operating system.

Zoho ManageEngine Desktop Central before build 100082 allows remote attackers to obtain control over all connected active desktops via unspecified vectors.

A remote code execution issue was discovered in Zoho ManageEngine Applications Manager before 13.6 (build 13640). The publicly accessible testCredential.do endpoint takes multiple user inputs and validates supplied credentials by accessing a specified system. This endpoint calls several internal classes, and then executes a PowerShell script. If the specified system is OfficeSharePointServer, then the username and password parameters to this script are not validated, leading to Command Injection.

Incorrect Access Control in CustomFieldsFeedServlet in Zoho ManageEngine Applications Manager Version 13 before build 13740 allows an attacker to delete any file and read certain files on the server in the context of the user (which by default is "NT AUTHORITY / SYSTEM") by sending a specially crafted request to the server.

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

An issue was discovered in Zoho ManageEngine Applications Manager 11.0 through 14.0. An unauthenticated user can gain the authority of SYSTEM on the server due to a Popup_SLA.jsp sid SQL injection vulnerability. For example, the attacker can subsequently write arbitrary text to a .vbs file.

Zoho ManageEngine Applications Manager 12 through 14 allows FaultTemplateOptions.jsp resourceid SQL injection. Subsequently, an unauthenticated user can gain the authority of SYSTEM on the server by uploading a malicious file via the "Execute Program Action(s)" feature.

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.

Zoho ManageEngine DataSecurity Plus prior to 6.0.1 uses default admin credentials to communicate with a DataEngine Xnode server. This allows an attacker to bypass authentication for this server and execute all operations in the context of admin user.

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.

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.

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. If an attacker specifies a Content-Length size of 1073741823 or larger, this integer arithmetic will wrap the value back around to smaller integer, then calls "calloc" with this size to allocate memory. The following API "InternetReadFile" will copy the POST data into this buffer, which will be too small for the contents, and cause heap overflow.

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

Zoho ManageEngine Desktop Central is vulnerable to authentication bypass, leading to remote code execution on the server, as exploited in the wild in December 2021. For Enterprise builds 10.1.2127.17 and earlier, upgrade to 10.1.2127.18. For Enterprise builds 10.1.2128.0 through 10.1.2137.2, upgrade to 10.1.2137.3. For MSP builds 10.1.2127.17 and earlier, upgrade to 10.1.2127.18. For MSP builds 10.1.2128.0 through 10.1.2137.2, upgrade to 10.1.2137.3.

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.

The DCPluginServelet servlet in ManageEngine Desktop Central and Desktop Central MSP before build 90109 allows remote attackers to create administrator accounts via an addPlugInUser action.

Manage Engine Desktop Central 9 before build 90135 allows remote attackers to change passwords of users with the Administrator role via an addOrModifyUser operation to servlets/DCOperationsServlet.

Zoho ManageEngine OpManager 11 through 12.2 uses a custom encryption algorithm to protect the credential used to access the monitored devices. The implemented algorithm doesn't use a per-system key or even a salt; therefore, it's possible to create a universal decryptor.

Directory traversal vulnerability in the file upload functionality in ZOHO WebNMS Framework 5.2 and 5.2 SP1 allows remote attackers to upload and execute arbitrary JSP files via a .. (dot dot) in the fileName parameter to servlets/FileUploadServlet.

ZOHO WebNMS Framework 5.2 and 5.2 SP1 use a weak obfuscation algorithm to store passwords, which allows context-dependent attackers to obtain cleartext passwords by leveraging access to WEB-INF/conf/securitydbData.xml. NOTE: this issue can be combined with CVE-2016-6601 for a remote exploit.

ZOHO WebNMS Framework 5.2 and 5.2 SP1 allows remote attackers to bypass authentication and impersonate arbitrary users via the UserName HTTP header.

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

Zoho ManageEngine Applications Manager 13 before build 13500 allows SQL injection via GraphicalView.do, as demonstrated by a crafted viewProps yCanvas field or viewid parameter.
