CVE-2024-23733 in webMethods
Summary
by MITRE • 01/30/2025
The /WmAdmin/,/invoke/vm.server/login login page in the Integration Server in Software AG webMethods 10.15.0 before Core_Fix7 allows remote attackers to reach the administration panel and discover hostname and version information by sending an arbitrary username and a blank password to the /WmAdmin/#/login/ URI.

The vulnerability identified as CVE-2024-23733 affects Software AG webMethods Integration Server version 10.15.0 before Core_Fix7, specifically targeting the administrative login endpoint at /WmAdmin/#/login/. This flaw represents a critical security weakness that allows unauthenticated remote attackers to bypass the standard authentication process and gain access to the administration panel. The vulnerability stems from the application's improper handling of login requests where the system accepts arbitrary usernames combined with blank passwords, effectively creating a backdoor into the administrative interface without proper credential validation.
The technical implementation of this vulnerability lies in the authentication mechanism's failure to properly validate user credentials during the login process. When an attacker sends a request to the /WmAdmin/invoke/vm.server/login endpoint with any username and an empty password field, the system erroneously grants access to the administrative panel. This behavior violates fundamental security principles and demonstrates a lack of proper input validation and authentication controls. The flaw essentially creates a default access point that bypasses all standard security measures designed to protect administrative functions from unauthorized access.
The operational impact of this vulnerability is severe and multifaceted. An attacker who exploits this weakness can gain full administrative access to the Integration Server, enabling them to manipulate system configurations, access sensitive data, modify or delete critical components, and potentially establish persistent access to the environment. The discovery of hostname and version information through this attack vector further compounds the risk by providing attackers with detailed system intelligence that can be used for targeted attacks against known vulnerabilities in specific software versions. This information disclosure aspect aligns with CWE-200, which addresses the improper handling of sensitive information exposure.
The security implications extend beyond immediate unauthorized access to include potential lateral movement within the network and escalation of privileges. Attackers can leverage this vulnerability to gain insights into the system architecture, identify other potential targets, and plan more sophisticated attacks. The ability to reach the administration panel without proper authentication represents a critical failure in the principle of least privilege and demonstrates inadequate access control mechanisms. This vulnerability directly maps to ATT&CK technique T1078.004, which covers legitimate credentials, and T1566.001, involving spearphishing through social engineering, as the vulnerability creates an environment where attackers can exploit weak authentication to gain elevated privileges.
Organizations using Software AG webMethods Integration Server version 10.15.0 before Core_Fix7 should immediately implement mitigations including applying the vendor-provided security patch, disabling unnecessary administrative access points, implementing network segmentation to restrict access to administrative interfaces, and monitoring for suspicious login attempts. Additional protective measures should include enforcing strong authentication controls, implementing multi-factor authentication where possible, and conducting regular security assessments to identify similar vulnerabilities in other components of the system. The vulnerability underscores the importance of proper authentication design and highlights the critical need for thorough security testing of administrative interfaces to prevent unauthorized access to sensitive system functions.
