CVE-2025-23458 is a high-severity vulnerability involving Improper Neutralization of Input During Web Page Generation, commonly known as a reflected Cross-Site Scripting (XSS) issue. It specifically affects the Rakessh Ads24 Lite plugin for WordPress (versions up to and including 1.0).
What It Is
- Vulnerability type: Reflected Cross-Site Scripting (XSS)
- Impact: An attacker can inject malicious scripts into web pages that are then executed in a victim’s browser. This can lead to credential theft, session hijacking, defacement, and other unwanted actions if a victim interacts with a crafted URL.
- Affected Software: Ads24 Lite (WordPress ad management plugin), versions <= 1.0.
Severity
- CVSS v3 Base Score:7.1 / High
- Attack Vector: Network
- Attack Complexity: Low
- Privileges Required: None
- User Interaction Required: Yes
- Impact: Confidentiality, Integrity, and Availability: Low to Moderate
- Variations in scoring exist among sources, but the vulnerability is generally treated at high severity.
How It Works
Reflected XSS means that user-supplied input (e.g., in a URL or form field) is improperly sanitized and then reflected back in the HTML response. An attacker can craft a malicious link that, when visited by a user (often an admin or site visitor), executes attacker-controlled JavaScript in the user’s browser.
Risks to Websites
Successful exploitation can lead to:
- Stealing login cookies or session tokens
- Redirection to malicious sites
- Phishing or unauthorized actions in the context of the user’s session
Mitigation & Fixes
To address this vulnerability:
- Update or remove Ads24 Lite plugin — move to a patched version once available, or switch to an alternative ad management plugin with proper input sanitization.
- Sanitize and validate all user input — ensure any data rendered in pages is properly escaped.
- Use a Web Application Firewall (WAF) — WAF rules can block reflected XSS patterns.
- Educate administrators and users — avoid clicking on untrusted URLs and follow security best practices.
