CVE-2026-112034 in iWebShop-5
Summary
by MITRE • 10/19/2026
A weakness has been identified in aircheng-org iWebShop-5 up to 5.16. The impacted element is the function IController::redirect of the file plugins/_userInfo/_userInfo.php of the component Login Redirect. This manipulation of the argument callback causes open redirect. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

The vulnerability identified in aircheng-org iWebShop versions up to 5.16 represents a critical security flaw within the Login Redirect component, specifically affecting the IController::redirect function located in the plugins/_userInfo/_userInfo.php file. This issue stems from an improper validation of user-supplied input passed as the callback argument during redirection operations. When the application processes this parameter without adequate sanitization or strict allow-listing of destination URLs, it permits attackers to manipulate the redirect target arbitrarily. This type of flaw is classically categorized under CWE-601, which defines URL Redirection to Untrusted Site (Open Redirect). The root cause lies in the failure to enforce domain restrictions on the output generated by the redirection logic, allowing external actors to inject malicious URLs that point to phishing sites or other harmful destinations.
From an operational perspective, this vulnerability enables remote attackers to execute social engineering attacks with high efficacy. By crafting a specially formatted URL containing the manipulated callback parameter, an attacker can trick users into believing they are still interacting with the legitimate iWebShop environment while being silently redirected to a malicious site controlled by the adversary. This technique is frequently employed in phishing campaigns where trust in the original domain is leveraged to lower user defenses before credential harvesting or malware distribution occurs. The presence of publicly available exploits significantly lowers the barrier for entry, allowing even less sophisticated threat actors to leverage this weakness against targeted organizations. Consequently, any instance of iWebShop running version 5.16 or earlier remains exposed to these risks until a patch is applied.
In terms of tactical classification within cybersecurity frameworks, this vulnerability aligns with ATT&CK technique T1189 Drive-by Compromise and potentially T1566 Phishing, as the open redirect serves as an initial vector for delivering malicious content under the guise of legitimacy. The lack of response from the project maintainers despite early notification via issue reports exacerbates the risk landscape, leaving users without official guidance or patches during a critical window of exposure. Organizations relying on this e-commerce platform must treat this vulnerability with high priority due to its remote exploitability and direct impact on user trust and data security.
Mitigation strategies should focus primarily on upgrading to a patched version once available from the project maintainers, ensuring that all instances are updated promptly upon release. In the interim, administrators can implement defensive measures at the web server or reverse proxy level by inspecting outgoing redirect headers for suspicious domains or non-internal URLs. Additionally, implementing strict Content Security Policy (CSP) directives and validating input parameters on both client and server sides can help mitigate the impact of such flaws. Regular security audits focusing on URL handling logic are recommended to identify similar patterns in other components that may share this architectural weakness.
