CVE-2014-0931

What is this vulnerability?

CVE-2014-0931 is categorized as a critical XML External Entity (XXE) flaw with a CVSS base score of 9.1. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

Multiple XML external entity (XXE) vulnerabilities in the (1) CCRC WAN Server / CM Server, (2) Perl CC/CQ integration trigger scripts, (3) CMAPI Java interface, (4) ClearCase remote client, and (5) CMI and OSLC-based ClearQuest integrations components in IBM Rational ClearCase 7.1.0.x, 7.1.1.x, 7.1.2 through 7.1.2.13, 8.0 through 8.0.0.10, and 8.0.1 through 8.0.1.3 allow remote attackers to cause a denial of service or access other servers via crafted XML data. IBM X-Force ID: 92263.

This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Risk Assessment

Impact on Systems

✅ Data Exfiltration: Attackers can extract sensitive data from backend databases, configuration files, or internal services.

✅ Authentication Bypass: Exploiting this flaw may allow unauthorized access to protected resources and administrative interfaces.

✅ Lateral Movement: Once initial access is gained, attackers can pivot to internal systems and escalate privileges.

How to Fix and Mitigate CVE-2014-0931

1. Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
2. Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
3. Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
4. Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

// ❌ VULNERABLE: XXE Injection
public void parseXml(InputStream is) throws Exception {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    // Taint sink: default configuration allows external entities
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.parse(is);
}

Secure Code Pattern

// ✅ SECURE: Safe XML Parsing
public void parseXml(InputStream is) throws Exception {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    // Sanitized configuration: disable external entities
    factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.parse(is);
}
