CVE-2015-3449 in Afaria
Summary
by MITRE
The Windows client in SAP Afaria 7.0.6398.0 uses weak permissions (Everyone: read and Everyone: write) for the install folder, which allows local users to gain privileges via a Trojan horse XeService.exe file.

The vulnerability identified as CVE-2015-3449 represents a critical privilege escalation flaw within the SAP Afaria 7.0.6398.0 Windows client installation. This issue stems from the installation directory configuration where the system employs overly permissive access controls that grant the Everyone group both read and write permissions. The weak permissions structure creates an exploitable condition that allows local attackers to manipulate the installation environment through malicious file placement.
The technical exploitation of this vulnerability occurs through a Trojan horse approach where an attacker places a malicious XeService.exe file within the vulnerable installation folder. This file manipulation technique leverages the weak permissions to overwrite or replace legitimate system files, ultimately enabling the execution of arbitrary code with elevated privileges. The flaw directly violates the principle of least privilege and demonstrates poor security configuration practices within the software installation process. The vulnerability is classified under CWE-276, which specifically addresses incorrect permissions for a resource, and represents a classic example of insecure default permissions that persist throughout the system lifecycle.
From an operational standpoint, this vulnerability presents a significant risk to enterprise environments that utilize SAP Afaria for mobile device management. Local users who might not have administrative privileges can exploit this weakness to escalate their access level and potentially gain full system control. The attack vector is particularly concerning because it requires minimal technical expertise to execute successfully, making it accessible to both malicious insiders and external attackers who have gained initial access to the system. This privilege escalation capability can lead to complete system compromise, data exfiltration, and further lateral movement within the network infrastructure.
The impact of this vulnerability extends beyond simple privilege escalation as it fundamentally undermines the security model of the affected system. Organizations using SAP Afaria 7.0.6398.0 face potential exposure to persistent threats that can maintain long-term access to their systems. The vulnerability also aligns with ATT&CK technique T1068, which covers "Exploitation for Privilege Escalation," demonstrating how weak permissions can serve as an entry point for more sophisticated attacks. Security professionals should consider this vulnerability as part of a broader exploitation chain that could lead to complete system compromise and data breaches.
Mitigation strategies for CVE-2015-3449 should focus on immediate permission adjustments to restrict write access to the installation directory. Organizations must implement proper access control lists that limit the Everyone group to read-only permissions and ensure that only authorized administrators can modify system files. Additionally, regular security audits should verify that installation directories maintain appropriate permissions and that no unauthorized modifications have occurred. The vulnerability highlights the importance of following security best practices such as implementing the principle of least privilege and conducting regular permission reviews. Organizations should also consider applying the latest security patches from SAP and implementing additional monitoring controls to detect unauthorized file modifications in critical system directories.
