CVE-2014-1407 in C54APM
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities on the Conceptronic C54APM access point with runtime code 1.26 allow remote attackers to inject arbitrary web script or HTML via (1) the submit-url parameter in a Refresh action to goform/formWlSiteSurvey or (2) the wlan-url parameter to goform/formWlanSetup.

The CVE-2014-1407 vulnerability represents a critical cross-site scripting flaw affecting the Conceptronic C54APM wireless access point running firmware version 1.26. This vulnerability resides within the web-based management interface of the device and demonstrates a classic input validation weakness that enables remote attackers to execute malicious code within the context of authenticated users. The flaw specifically manifests in two distinct attack vectors that target different form processing endpoints within the device's administration interface.
The technical implementation of this vulnerability stems from insufficient sanitization of user-supplied input parameters within the web application's form handling mechanisms. Attackers can exploit the submit-url parameter in the Refresh action to goform/formWlSiteSurvey and the wlan-url parameter in goform/formWlanSetup to inject malicious scripts. These parameters are directly incorporated into the web response without proper output encoding or validation, creating an environment where attacker-controlled content can be executed in the victim's browser context. The vulnerability is particularly concerning as it operates at the application layer and requires no authentication to exploit, making it accessible to any remote attacker.
The operational impact of this vulnerability extends beyond simple script injection, as it provides attackers with the capability to perform session hijacking, steal sensitive administrative credentials, and potentially gain full control over the wireless access point. An attacker could craft malicious URLs that, when visited by an authenticated administrator, would execute scripts to steal cookies, redirect users to malicious sites, or even modify network configurations. The vulnerability effectively compromises the integrity of the device's web interface and undermines the security model of the access point, as it allows for persistent malicious activities that could persist across multiple user sessions.
Mitigation strategies for this vulnerability should include immediate firmware updates from the vendor to address the input validation flaws, network segmentation to limit access to the management interface, and implementation of web application firewalls to detect and block malicious input patterns. Organizations should also consider disabling unnecessary web management interfaces and implementing strict access controls through network ACLs. This vulnerability aligns with CWE-79 which describes cross-site scripting flaws, and maps to ATT&CK technique T1059.007 for command and script injection, highlighting the need for comprehensive input validation and output encoding practices. The remediation process should also involve thorough security testing of all web interfaces to identify similar vulnerabilities in other network equipment that may be running outdated firmware versions.
