The vulnerability identified as CVE-2013-2095 affects the rubygem-openshift-origin-controller component within the OpenShift platform, specifically targeting the application creation functionality through the cartridge_cache.rb file. This issue arises from improper input validation within the URI.parse() method implementation, which creates a command injection vector that attackers can exploit to execute arbitrary commands on the system. The vulnerability is particularly concerning as it allows unauthorized users to leverage the API endpoint designed for legitimate application creation processes to gain elevated privileges and execute malicious code.
The technical flaw stems from the insecure handling of URI parsing operations within the cartridge_cache.rb file, where the application fails to properly sanitize user-provided input before processing it through the URI.parse() function. When malicious input is passed to this function, the system interprets certain characters and sequences as command execution directives rather than simple URI components. This occurs because the implementation does not adequately validate or escape special characters that could be interpreted by the underlying system shell, creating a classic command injection vulnerability. The flaw aligns with CWE-77 and CWE-94 categories, representing command injection and code injection weaknesses respectively, where user-controllable data flows directly into system execution contexts without proper sanitization.
The operational impact of this vulnerability is significant for OpenShift platform administrators and users, as successful exploitation could result in complete system compromise. Attackers could leverage this vulnerability to execute arbitrary commands with the privileges of the affected application process, potentially leading to data theft, service disruption, or further lateral movement within the network. The vulnerability affects the core application creation functionality, making it particularly dangerous as it could be exploited by both authenticated and unauthenticated users depending on the platform configuration. This type of vulnerability directly maps to ATT&CK technique T1059.001 for command and script injection, and T1068 for exploit for privilege escalation, representing a serious threat to platform security and integrity.
Mitigation strategies for CVE-2013-2095 should focus on immediate input validation and sanitization measures within the cartridge_cache.rb file. The primary remediation involves implementing proper input sanitization before any URI parsing operations, ensuring that all user-provided data is validated against expected formats and character sets. Organizations should also implement proper access controls and authentication mechanisms to limit API exposure, while applying the latest security patches from Red Hat and OpenShift maintainers. Additionally, network segmentation and monitoring should be implemented to detect anomalous command execution patterns that might indicate exploitation attempts. The vulnerability highlights the importance of secure coding practices and input validation, particularly when dealing with system-level operations and user-provided data that could potentially be interpreted as shell commands.
