CVE-2025-68835 is a reflected Cross-site Scripting (XSS) vulnerability found in the matiskiba Ravpage web application, affecting versions up to and including 2.33. The vulnerability stems from improper neutralization of user-supplied input during the dynamic generation of web pages, allowing malicious scripts to be injected and executed in the context of a victim's browser. This type of vulnerability enables attackers to perform a range of malicious activities such as stealing session cookies, defacing websites, redirecting users to phishing or malware sites, and executing arbitrary JavaScript code. The vulnerability is exploitable remotely over the network without requiring any privileges (AV:N/PR:N), but it does require user interaction (UI:R), such as clicking on a specially crafted URL. The CVSS v3.1 base score is 7.1, reflecting high severity due to the combined impact on confidentiality, integrity, and availability, and the low attack complexity. The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. No patches or known exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly. The affected product, Ravpage, is a web content management system used for creating and managing websites, which makes the vulnerability particularly critical for organizations relying on it for public-facing or internal web portals. The vulnerability's presence in web page generation logic suggests that input sanitization and output encoding are insufficient or missing, a common cause of reflected XSS issues. This vulnerability can be leveraged in phishing campaigns or targeted attacks to compromise user sessions or deliver secondary payloads.

For European organizations, the impact of CVE-2025-68835 can be significant, especially for those using Ravpage as part of their web infrastructure. Successful exploitation can lead to theft of user credentials or session tokens, enabling unauthorized access to sensitive information or administrative functions. It can also facilitate website defacement or redirect users to malicious sites, damaging organizational reputation and trust. The availability of services may be disrupted if attackers inject scripts that cause browser crashes or denial of service. Given the vulnerability requires user interaction, phishing or social engineering campaigns could be used to increase success rates. Organizations in sectors such as government, finance, healthcare, and media that rely on Ravpage for public-facing websites are particularly at risk. The cross-site scripting flaw can also serve as a foothold for further attacks, including malware distribution or lateral movement within internal networks. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread abuse occurs.

To mitigate CVE-2025-68835, organizations should first check for and apply any available patches or updates from matiskiba for Ravpage. In the absence of official patches, implement strict input validation on all user-supplied data to ensure that potentially malicious characters are sanitized or rejected. Employ comprehensive output encoding (e.g., HTML entity encoding) when reflecting user input in web pages to prevent script execution. Deploy a robust Content Security Policy (CSP) that restricts the execution of inline scripts and limits sources of executable code. Use security headers such as X-XSS-Protection and HTTPOnly cookies to reduce attack surface. Conduct regular security assessments and penetration testing focused on XSS vulnerabilities. Educate users and administrators about the risks of clicking on suspicious links and the importance of verifying URLs. Monitor web server logs and intrusion detection systems for anomalous requests indicative of exploitation attempts. Consider implementing web application firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting Ravpage. Finally, plan for incident response procedures in case exploitation is detected.
