Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Aakif Kadiwala Posts Slider Shortcode allows DOM-Based XSS. This issue affects Posts Slider Shortcode: from n/a through 1.0.
AI Analysis
Technical Summary
CVE-2025-30943 is a Cross-site Scripting (XSS) vulnerability classified under CWE-79, specifically an improper neutralization of input during web page generation. This vulnerability affects the 'Posts Slider Shortcode' product developed by Aakif Kadiwala. The flaw allows for DOM-based XSS attacks, meaning that malicious scripts can be injected and executed in the context of a user's browser when interacting with the vulnerable shortcode. The vulnerability is present in versions up to 1.0, with no specific version range detailed. The CVSS 3.1 score is 6.5 (medium severity), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, indicating that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary. The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent. No known exploits are reported in the wild, and no patches have been linked yet. The vulnerability arises because the input is not properly sanitized or encoded before being used in the DOM during page generation, allowing attackers to craft payloads that execute arbitrary JavaScript in the victim's browser. This can lead to session hijacking, defacement, or redirection to malicious sites.
Potential Impact
For European organizations, the impact of this vulnerability depends largely on the usage of the Posts Slider Shortcode plugin within their web infrastructure, typically WordPress-based sites. Exploitation could allow attackers to execute arbitrary scripts in the context of users visiting affected sites, potentially leading to theft of session cookies, user credentials, or performing actions on behalf of users (such as changing settings or injecting further malicious content). This can damage brand reputation, lead to data breaches involving personal data protected under GDPR, and cause service disruptions. Since the scope is changed, the attack could affect other components or services interacting with the vulnerable plugin. The requirement for user interaction (clicking or visiting a crafted link) means phishing or social engineering could be used to trigger the exploit. Given the medium severity and the lack of known exploits, the immediate risk is moderate but should not be underestimated, especially for organizations with high web traffic or sensitive user data.
Mitigation Recommendations
1. Immediate review and removal or disabling of the Posts Slider Shortcode plugin until a patch is available. 2. Implement Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce the impact of XSS. 3. Sanitize and encode all user inputs and outputs rigorously, especially those handled by the shortcode, to prevent injection of malicious scripts. 4. Monitor web application logs for unusual activity or attempts to exploit XSS vectors. 5. Educate users and administrators about the risks of clicking on suspicious links and the importance of applying updates promptly. 6. Use web application firewalls (WAFs) with rules targeting XSS attack patterns to provide an additional layer of defense. 7. Once a patch or update is released by the vendor, prioritize its deployment after testing in a staging environment. 8. Conduct security testing (including automated scanning and manual penetration testing) focused on DOM-based XSS vulnerabilities in web applications.
