CVE-2025-58261 is a high-severity vulnerability identified in the PressPage Entertainment Inc product named Mavis HTTPS to HTTP Redirection, affecting versions up to 1.4.3. The vulnerability is classified as a Cross-Site Request Forgery (CSRF) issue (CWE-352) that enables an attacker to perform unauthorized actions on behalf of an authenticated user. Specifically, this CSRF vulnerability facilitates a Stored Cross-Site Scripting (XSS) attack vector, where malicious scripts can be injected and persistently stored via the HTTPS to HTTP redirection mechanism. This redirection component is intended to downgrade HTTPS requests to HTTP, which itself is a risky practice, potentially exposing sensitive data or session tokens to interception. The CVSS 3.1 base score of 7.1 indicates a high severity, with the vector string AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L meaning the attack can be launched remotely over the network with low attack complexity, no privileges required, but requires user interaction. The scope is changed (S:C), indicating the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent (low impact on confidentiality, integrity, and availability). The vulnerability has been published recently (September 2025) and no known exploits are currently observed in the wild. The lack of available patches at the time of publication increases the urgency for mitigation. The combination of CSRF and stored XSS in a redirection service is particularly dangerous because it can be used to hijack user sessions, steal credentials, or perform unauthorized actions silently, potentially compromising the security posture of web applications relying on this redirection service.

For European organizations, the impact of this vulnerability can be significant, especially for those using PressPage Entertainment Inc's Mavis HTTPS to HTTP Redirection service as part of their web infrastructure. The CSRF enabling stored XSS can lead to session hijacking, unauthorized command execution, and data leakage. This can compromise user accounts, lead to defacement or manipulation of web content, and potentially facilitate further attacks such as phishing or malware distribution. Given the redirection from HTTPS to HTTP, sensitive information may be exposed to network attackers, increasing the risk of man-in-the-middle attacks. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, may face compliance violations and reputational damage if exploited. Additionally, the requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit, increasing the attack surface. The absence of patches means organizations must rely on interim mitigations, increasing operational complexity and risk exposure until a fix is available.

1. Immediately audit and monitor all instances of Mavis HTTPS to HTTP Redirection within the organization's infrastructure to identify affected versions. 2. Disable or restrict the use of HTTPS to HTTP redirection wherever possible, as downgrading secure connections inherently introduces risk. 3. Implement strict Content Security Policy (CSP) headers to mitigate the impact of stored XSS by restricting the execution of unauthorized scripts. 4. Employ anti-CSRF tokens and verify the origin and referer headers on all state-changing requests to prevent CSRF attacks. 5. Educate users to recognize and avoid suspicious links or requests that could trigger CSRF or XSS attacks, reducing the risk of user interaction exploitation. 6. Use Web Application Firewalls (WAFs) with updated rules to detect and block CSRF and XSS attack patterns targeting this vulnerability. 7. Monitor network traffic for unusual HTTP downgrade attempts and anomalous request patterns indicative of exploitation attempts. 8. Engage with PressPage Entertainment Inc for timely patch releases and apply updates as soon as they become available. 9. Consider isolating or sandboxing the affected service to limit the blast radius in case of exploitation. 10. Conduct regular security assessments and penetration testing focusing on web redirection components to identify residual risks.
