CVE-2016-0364 in UrbanCode Deploy
Summary
by MITRE
IBM UrbanCode Deploy 6.0.x before 6.0.1.13, 6.1.x before 6.1.3.3, and 6.2.x before 6.2.1.1 does not properly implement a logging-obfuscation feature for secure properties, which allows remote authenticated users to obtain sensitive information via vectors involving special characters.

IBM UrbanCode Deploy versions 6.0.x before 6.0.1.13, 6.1.x before 6.1.3.3, and 6.2.x before 6.2.1.1 contain a critical security flaw in their logging obfuscation implementation for secure properties. This vulnerability stems from inadequate handling of special characters within the logging system, which fails to properly mask sensitive data during log generation processes. The flaw exists in the software's attempt to protect confidential information by obfuscating it in log files, yet the implementation contains a significant gap that allows authenticated attackers to bypass these protective measures. Attackers can exploit this weakness by crafting specific inputs containing special characters that manipulate the logging system's behavior, ultimately revealing sensitive information that should have been obscured.
The technical nature of this vulnerability aligns with CWE-200, which addresses "Information Exposure," and specifically relates to improper logging obfuscation mechanisms. This weakness enables attackers to extract confidential data through manipulation of the logging infrastructure, representing a direct violation of data protection principles. The vulnerability operates at the application level within the UrbanCode Deploy platform, where secure properties such as passwords, API keys, and other sensitive credentials are processed through logging functions. The flaw manifests when the system processes special characters in property values, causing the obfuscation logic to fail and expose raw sensitive data in log outputs. This represents a classic case of insufficient input sanitization combined with inadequate output filtering in security-critical components.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with access to potentially critical system credentials and configuration details that could enable further exploitation. An authenticated attacker with access to the UrbanCode Deploy system can leverage this vulnerability to gain insights into system security configurations, user credentials, and other sensitive operational data that would normally be protected. The exposure of such information could facilitate privilege escalation attacks, lateral movement within the infrastructure, or even complete system compromise depending on the nature of the exposed credentials. This vulnerability particularly affects organizations relying on UrbanCode Deploy for application deployment management, as it undermines the security controls designed to protect sensitive deployment configurations and access credentials.
Organizations should immediately apply the vendor-provided patches for versions 6.0.1.13, 6.1.3.3, and 6.2.1.1 to remediate this vulnerability. The mitigation strategy should include comprehensive log review processes to identify any potential exposure of sensitive data that may have occurred prior to patch application. Security teams should implement additional monitoring of log files for unusual patterns that might indicate exploitation attempts, and consider implementing more robust log obfuscation mechanisms beyond the default implementation. The vulnerability demonstrates the importance of proper input validation and output sanitization in security-critical applications, particularly in deployment and configuration management systems where sensitive data is routinely processed. Organizations should also consider implementing principle of least privilege access controls for UrbanCode Deploy systems and regularly audit access permissions to minimize potential damage from any successful exploitation attempts. This vulnerability serves as a reminder of the critical importance of proper security implementation in logging systems, as these components often serve as attack vectors for information disclosure and privilege escalation attacks.
