CVE-2024-47113 Overview
CVE-2024-47113 is an XML Injection vulnerability affecting IBM ICP - Voice Gateway across multiple versions. The vulnerability allows remote attackers to send specially crafted XML statements to the Voice Gateway, enabling them to view or modify information within XML documents processed by the application. This type of vulnerability, classified under CWE-91 (XML Injection), occurs when untrusted data is improperly processed within XML structures, potentially allowing attackers to manipulate XML document content or structure.
Critical Impact
Remote attackers can exploit this vulnerability without authentication to view sensitive information or modify XML document data, potentially compromising the confidentiality and integrity of the Voice Gateway system.

Technical Details for CVE-2024-47113
Vulnerability Analysis
This XML Injection vulnerability in IBM Voice Gateway stems from improper handling of user-supplied input within XML processing routines. The Voice Gateway application fails to adequately sanitize or validate XML data before processing, allowing attackers to inject malicious XML content. When exploited, this can lead to unauthorized access to sensitive data stored in XML documents or the ability to modify XML document content, which could affect the behavior and configuration of the Voice Gateway system.
The vulnerability is exploitable remotely over the network without requiring any user interaction or prior authentication. This makes it particularly dangerous in enterprise environments where Voice Gateway systems may be exposed to potentially hostile network traffic.
Root Cause
The root cause of CVE-2024-47113 is improper input validation of XML data (CWE-91). The IBM Voice Gateway application does not properly sanitize user-controlled input before incorporating it into XML documents or queries. This allows attackers to inject arbitrary XML elements, attributes, or syntax that the parser interprets as legitimate XML content rather than user data. The lack of proper input encoding, validation, or the use of safe XML APIs enables this attack vector.
Attack Vector
The attack can be conducted remotely over the network. An attacker can craft malicious XML payloads containing injected XML elements or modified document structures and send them to the Voice Gateway. The vulnerable application processes these payloads without adequate validation, executing the attacker's injected XML content. This can result in:
- Information Disclosure: Accessing sensitive configuration data, credentials, or other confidential information stored in XML documents
- Data Modification: Altering XML document content to change application behavior, configurations, or stored data
- Potential Service Disruption: Corrupting XML data structures critical to Voice Gateway operations
The vulnerability requires no authentication and no user interaction, making exploitation straightforward for attackers with network access to the Voice Gateway system.
Detection Methods for CVE-2024-47113
Indicators of Compromise
- Unusual or malformed XML requests in Voice Gateway application logs
- Unexpected modifications to XML configuration files or data stores
- Error messages indicating XML parsing failures or injection attempts
- Anomalous network traffic patterns targeting Voice Gateway XML endpoints
Detection Strategies
- Monitor application logs for suspicious XML content containing unexpected elements or encoding
- Implement web application firewall (WAF) rules to detect common XML injection patterns
- Deploy network intrusion detection systems (IDS) with signatures for XML injection attacks
- Review Voice Gateway audit logs for unauthorized configuration changes
Monitoring Recommendations
- Enable detailed logging for all XML processing operations in the Voice Gateway
- Configure alerts for failed XML parsing attempts that may indicate exploitation attempts
- Monitor for changes to XML documents and configurations outside of approved change windows
- Implement file integrity monitoring for critical XML-based configuration files
How to Mitigate CVE-2024-47113
Immediate Actions Required
- Review the IBM Security Advisory for official patch information
- Identify all IBM Voice Gateway instances running affected versions (1.0.2 through 1.0.8)
- Restrict network access to Voice Gateway systems to trusted networks only
- Implement input validation at network perimeter using WAF rules for XML injection
Patch Information
IBM has released a security advisory addressing this vulnerability. Organizations should consult the IBM Support Page for the latest patch information and upgrade instructions. Administrators should prioritize patching given the critical severity rating and the ability for remote unauthenticated exploitation.
Workarounds
- Implement strict network segmentation to limit access to Voice Gateway systems
- Deploy a web application firewall (WAF) configured with XML injection detection rules
- Enable input validation and sanitization at application entry points where possible
- Consider temporarily disabling affected XML processing features if business operations permit
- Monitor Voice Gateway systems closely for any signs of exploitation while awaiting patch deployment
