The vulnerability identified as CVE-2013-3315 resides within the TIBCO Silver Mobile 1.1.0 server component, representing a critical access control flaw that undermines the application's security model. This issue manifests as an insufficient authorization check mechanism that fails to properly validate administrative privileges before executing sensitive commands. The vulnerability affects the server-side implementation where authenticated users can exploit a privilege escalation vector to gain elevated access rights, potentially compromising the entire mobile application infrastructure. The flaw exists in the authentication and authorization framework, specifically in how the system handles role verification during command execution processes.
The technical implementation of this vulnerability stems from improper access control validation within the TIBCO Silver Mobile server's administrative interface. When authenticated users attempt to execute administrative commands, the system should verify that the requesting user possesses the necessary administrator role before proceeding with the operation. However, the current implementation lacks robust role verification mechanisms, allowing authenticated users to bypass these security checks through unspecified vectors. This represents a classic privilege escalation vulnerability that aligns with CWE-285, which addresses improper authorization in software systems. The vulnerability's impact extends beyond simple access control as it enables attackers to manipulate administrative functions and potentially compromise the entire mobile platform.
From an operational perspective, this vulnerability presents a significant risk to organizations utilizing TIBCO Silver Mobile 1.1.0 for enterprise mobile solutions. An authenticated attacker who gains access to any user account can exploit this flaw to elevate their privileges and assume administrative control over the mobile server. This compromise could enable attackers to modify system configurations, access sensitive data, manipulate user accounts, and potentially disrupt mobile application services. The attack vector is particularly concerning because it requires only authentication, making it accessible to users who may not have legitimate administrative access. The vulnerability essentially creates a backdoor for privilege escalation that could be exploited by both internal and external threat actors.
Organizations should implement immediate mitigations to address this vulnerability, including applying the vendor-provided security patches or upgrading to patched versions of TIBCO Silver Mobile. Network segmentation and access control measures can help limit the potential impact by restricting access to administrative functions. Additionally, implementing proper monitoring and logging of administrative activities can aid in detecting unauthorized privilege escalation attempts. The vulnerability's characteristics align with ATT&CK technique T1078 which covers valid accounts and privilege escalation, making it essential for security teams to monitor for suspicious administrative activities. Regular security assessments and penetration testing should be conducted to identify similar authorization flaws in other enterprise mobile applications and systems. Organizations should also consider implementing principle of least privilege configurations and multi-factor authentication to reduce the attack surface and limit the potential damage from such vulnerabilities.
