The vulnerability identified as CVE-2018-2490 affects SAP Fiori Client version 1.11.5 and relates to insufficient permission controls over broadcast messages within the application. This security flaw exists in the Android implementation of SAP Fiori Client which is distributed through the Google Play store. The issue stems from the application's failure to properly validate or restrict access to broadcast messages that are received by the client component, creating potential attack vectors for malicious actors who can exploit this weakness to send unauthorized messages to the application.
The technical implementation of this vulnerability involves the application's broadcast receiver components not enforcing proper access controls or permission checks before processing incoming messages. According to CWE-284, this represents an inadequate access control mechanism where the application fails to properly restrict access to its broadcast message handling components. The flaw allows for potential privilege escalation and unauthorized data manipulation through the broadcast message system, as the application does not validate whether incoming messages originate from trusted sources or possess appropriate authorization levels.
From an operational perspective, this vulnerability creates significant security implications for organizations using SAP Fiori Client for mobile enterprise applications. Attackers who can send malicious broadcast messages to the application may potentially execute unauthorized operations, access sensitive data, or manipulate application behavior without proper authentication. The impact extends beyond simple data exposure to potentially enabling more severe attacks such as remote code execution or complete application compromise, especially when combined with other vulnerabilities in the mobile application stack. This weakness particularly affects enterprise environments where SAP Fiori Client is used for mission-critical business applications.
The recommended mitigation strategy involves immediate deployment of SAP Fiori Client version 1.11.5 which addresses this specific vulnerability through proper broadcast message permission controls. Organizations should implement comprehensive mobile application management policies to ensure all users are updated to the patched version. The remediation aligns with ATT&CK technique T1059.007 for command and scripting interpreter usage, as the vulnerability could potentially enable adversaries to execute malicious commands through crafted broadcast messages. Security teams should also conduct vulnerability assessments to identify any other broadcast message handling components within their mobile application ecosystem that might exhibit similar permission control weaknesses, following the principle of least privilege enforcement as outlined in cybersecurity frameworks such as NIST SP 800-53.
