CVE-2025-4652 Scanner

The Broadstreet WordPress plugin is used by various WordPress-based websites for managing online advertisements and increasing advertising efficiency. It is a popular plugin due to its robust features that allow easy management and integration with other WordPress functions. Users, often website administrators and digital marketers, utilize this plugin to optimize their advertisement strategies. The primary purpose of the Broadstreet plugin is to control advertising spaces, manage client campaigns, and generate performance reports. It is widely implemented in websites to improve advertisement logistics and audience engagement. Its comprehensive toolkit also provides options for customization and analytics, catering to the needs of business-oriented WordPress users.

Cross-Site Scripting (XSS) is a type of web security vulnerability that allows attackers to introduce and execute scripts in the browsers of users visiting a vulnerable website. The vulnerability in question is a reflected XSS, which occurs when input received via an HTTP request is included in the response without proper execution restrictions. With reflected XSS, malicious scripts are executed on the client side while interactions with a website occur. This vulnerability could potentially allow attackers to execute unauthorized scripts, leading to session hijacking, unauthorized actions, or data theft. It is critical in scenarios where a script runs with the permissions of a high-privilege user, such as an admin.

In the case of the Broadstreet WordPress plugin, the vulnerability exists within a specific page that does not adequately sanitize its inputs. The vulnerable parameters are located in the URL, particularly within the query string, where they are directly reflected in the HTML response output. This unsanitized input is embedded into a script tag, which is subsequently executed in the victim's browser if interacted with. The technical root of this vulnerability lies in insufficient input validation, where the inclusion of malicious script contents is allowed within visible output areas of the web page. Such issues arise due to overlooking strict output encoding and sanitization practices.

When exploited, this vulnerability enables attackers to execute scripts that can capture administrator session tokens, manipulate site content, or commandeer user actions without consent. Attackers can leverage the scripts to target sensitive interactions and facilitate further exploitation efforts, potentially leading to complete site takeover or significant security breaches. This can affect website integrity, expose confidential data, and compromise trust among users and administrators. Remediation is essential to prevent unwarranted access and ensure continuous web service security.
