CVE-2015-1487 in Endpoint Protection Manager
Summary
by MITRE
The management console in Symantec Endpoint Protection Manager (SEPM) 12.1 before 12.1-RU6-MP1 allows remote authenticated users to write to arbitrary files, and consequently obtain administrator privileges, via a crafted filename.

The vulnerability identified as CVE-2015-1487 resides within the Symantec Endpoint Protection Manager (SEPM) version 12.1 prior to 12.1-RU6-MP1, representing a critical security flaw that enables remote authenticated attackers to execute arbitrary file writes and subsequently escalate their privileges to administrator level access. This issue manifests through the management console component of the SEPM software, which serves as the centralized interface for administrators to manage endpoint protection policies and configurations across enterprise networks.
The technical exploitation of this vulnerability stems from inadequate input validation within the file handling mechanisms of the SEPM management console. Attackers who have already gained authenticated access to the system can craft malicious filenames that bypass normal security restrictions, allowing them to write files to arbitrary locations on the server filesystem. This privilege escalation occurs because the application fails to properly sanitize user-supplied filenames, enabling attackers to manipulate the file system write operations and place malicious code in critical system directories. The flaw operates at the application level, specifically targeting the file manipulation functions that are exposed through the web-based management interface.
The operational impact of CVE-2015-1487 extends far beyond simple privilege escalation, as it provides attackers with complete administrative control over the SEPM server and by extension, the entire endpoint protection infrastructure it manages. Once an attacker achieves administrator privileges, they can modify or delete critical security policies, disable protection mechanisms, install backdoors, and potentially compromise the entire network security posture. This vulnerability directly undermines the security architecture of organizations relying on Symantec Endpoint Protection Manager, as it allows attackers to subvert the centralized management capabilities that are designed to enhance security rather than weaken it. The implications are particularly severe in enterprise environments where SEPM serves as the primary security management platform for thousands of endpoints.
Organizations affected by this vulnerability should immediately apply the vendor-provided patch releases including 12.1-RU6-MP1 and subsequent updates to remediate the issue. Security teams should also implement network monitoring to detect suspicious file write activities and consider isolating the SEPM server in a segmented network environment to limit potential attack vectors. The vulnerability aligns with CWE-22, which addresses path traversal flaws in file system operations, and represents a clear violation of the principle of least privilege as defined in cybersecurity frameworks. From an ATT&CK perspective, this vulnerability maps to privilege escalation techniques and can be leveraged for persistence and lateral movement within compromised networks, making it a critical target for immediate remediation and monitoring efforts.
