A joint Cybersecurity Advisory examines the exploitation of two critical vulnerabilities by nation-state threat actors.

AA23-250A: Multiple Nation-State Threat Actors Exploit CVE-2022-47966 and CVE-2022-42475

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).

A remote code execution vulnerability exists in ManageEngine ServiceDesk Plus prior to 14.0 Build 14004 due to use of Apache 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version   number.

The ManageEngine Access Manager Plus running on the remote host is affected by a remote code execution vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to execute arbitrary code.

The ManageEngine ServiceDesk Plus MSP running on the remote host is affected by a remote code execution vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to execute arbitrary code.

This plugin requires that both the scanner and target machine have internet access.

Multiple Zoho ManageEngine OnPremise products use an outdated Apache Santuario (xmlsec) component which fails to properly validate XML signatures of SAML responses received during the authentication flow. By crafting a specific HTTP request containing a malicious XML payload and sending it to the vulnerable product Assertion Consumer (ACS) URL, an attacker could achieve a remote unauthenticated Remote Code Execution (RCE) on the target instance.
