Directory Traversal in Linksys E1500 apply.cgi

IdentifiersCVE-2013-10062CWE-22· Improper Limitation of a Pathname…

CVE-2013-10062 is a directory traversal vulnerability in the Linksys router web interface, confirmed on the E1500 model with firmware versions 1.0.00, 1.0.04, and 1.0.05. The flaw is present in the /apply.cgi endpoint, where the next_page POST parameter is not properly restricted to the intended web root. An authenticated attacker can supply traversal sequences in next_page to cause the application to access files outside the expected directory scope. As a result, arbitrary local files, including sensitive system files and router configuration data, may be exposed through the web interface.

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 authenticated attacker to read arbitrary files accessible to the vulnerable web application outside the intended web root. This can expose sensitive system information and device configuration data, which may include operational details useful for further compromise. Based on the provided information, the primary impact is unauthorized file disclosure rather than direct code execution or privilege escalation.

Mitigation

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

Restrict access to the router administrative web interface to trusted management networks only, disable remote administration from untrusted networks, and ensure strong authentication is enforced for administrative access. Network segmentation and firewall rules should be used to prevent unauthorized reachability to the management interface. Monitoring for suspicious requests to /apply.cgi containing traversal patterns in the next_page parameter may help detect exploitation attempts.

Remediation

Patch, then assume compromise.

Upgrade the affected Linksys E1500 firmware to a vendor-fixed version if one is available. The vulnerable /apply.cgi handling of the next_page parameter should be corrected by enforcing strict path validation, rejecting traversal sequences, and restricting file access to an allowlisted set of expected resources within the web root. If no fixed firmware is available, replacement with a supported device or firmware should be considered.

linksys_e1500_traversal.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit auxiliary scanner module targeting a directory traversal vulnerability in Linksys E1500 routers (CVE-2013-10062). The module attempts to authenticate to the router's web interface (default credentials: admin/password) and then sends crafted HTTP POST requests to the /apply.cgi endpoint, exploiting a directory traversal flaw in the next_page parameter. The module reads a list of sensitive file paths from a wordlist (sensitive_files.txt) and attempts to retrieve each file from the router, storing any successful results as loot. The code is written in Ruby and is structured as a typical Metasploit module, including references to the vulnerability and configuration options for credentials and file lists. The main attack vector is network-based, targeting the router's HTTP interface. No fake or detection-only code is present; this is a functional exploit module.
