Path Traversal in Symantec Endpoint Protection Manager (SEPM) 12.1

IdentifiersCVE-2015-1487CWE-22

CVE-2015-1487 is a path traversal vulnerability in the management console of Symantec Endpoint Protection Manager (SEPM) 12.1 prior to 12.1-RU6-MP1. The vulnerability allows remote authenticated users to write arbitrary files to the filesystem by supplying crafted filenames to the UploadPackage action. This can be exploited to upload malicious files, such as a JSP web shell, to the SEPM server, enabling further attacks.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker to write arbitrary files to the SEPM server, which can be leveraged to obtain administrator privileges and execute arbitrary code with 'NT Service\semsrv' privileges. Combined with other vulnerabilities (e.g., privilege escalation), this can lead to full compromise of the SEPM server and potentially the entire corporate network, especially if the SEPM server is exposed to the network.

Mitigation

If you can’t patch tonight, do this now.

Restrict network access to the SEPM management console interfaces (TCP ports 8443 and 9090) to trusted administrators only. Monitor for suspicious file uploads and review server logs for signs of exploitation. Disable or tightly control the UploadPackage functionality if possible until the patch is applied.

Remediation

Patch, then assume compromise.

Upgrade Symantec Endpoint Protection Manager to version 12.1 RU6 MP1 or later, as the vulnerability is addressed in SYM15-007. Ensure all management servers are updated and verify that no unauthorized files have been uploaded to the server.

sepm_auth_bypass_rce.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (modules/exploits/windows/http/sepm_auth_bypass_rce.rb) targeting Symantec Endpoint Protection Manager (SEPM) for Windows. The exploit leverages three vulnerabilities (authentication bypass, directory traversal, and privilege escalation) to achieve remote code execution as NT AUTHORITY\SYSTEM. The module interacts with the SEPM web interface (typically over HTTPS on port 8443), first bypassing authentication to obtain a session cookie, then uploading a custom payload (Windows executable) and a malicious JSP via directory traversal. The JSP is then triggered to execute the payload, providing the attacker with a remote shell. The exploit is weaponized, allowing for customizable payloads via the Metasploit framework. The main fingerprintable endpoint is the '/servlet/ConsoleServlet' path on the SEPM web server, and the exploit uploads files to the 'tomcat/webapps/ROOT/' directory on the target. The repository is structured as a typical Metasploit module, written in Ruby, and is intended for use within the Metasploit framework.
