CVE-2025-14692 is an open redirect vulnerability affecting Mayan EDMS, an open-source electronic document management system widely used for managing and storing documents securely. The flaw exists in an unspecified function within the /authentication/ path, allowing an attacker to craft URLs that redirect users to arbitrary external sites. This vulnerability can be exploited remotely without authentication, requiring only that a user clicks a malicious link. The open redirect can be leveraged in phishing campaigns to trick users into visiting malicious websites, potentially leading to credential theft, malware infection, or further social engineering attacks. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:P), and limited impact on integrity (VI:L) with no impact on confidentiality or availability. The vendor has addressed the issue in version 4.10.2 and is preparing backports for older supported versions. Although no active exploitation has been reported, the public availability of an exploit increases the urgency for patching. The vulnerability highlights the importance of validating and sanitizing redirect URLs in authentication workflows to prevent abuse.

For European organizations, the open redirect vulnerability poses a significant risk primarily through phishing and social engineering attacks. Attackers can exploit this flaw to redirect users to malicious websites that may harvest credentials or deliver malware, undermining user trust and potentially leading to unauthorized access to sensitive documents managed by Mayan EDMS. Given the critical role of document management systems in compliance-heavy sectors such as finance, healthcare, and government, exploitation could result in data breaches, regulatory penalties under GDPR, and reputational damage. The medium CVSS score reflects moderate impact but the ease of exploitation and lack of required privileges increase the threat surface. Organizations relying on Mayan EDMS for secure document workflows may face increased risk of targeted attacks, especially if users are not trained to recognize suspicious links. The vulnerability does not directly compromise system integrity or availability but serves as an effective vector for broader attacks.

European organizations should immediately upgrade all Mayan EDMS installations to version 4.10.2 or later to remediate the vulnerability. For environments where immediate upgrade is not feasible, implement strict URL validation and filtering on the authentication redirect parameters to block untrusted or external URLs. Employ web application firewalls (WAFs) with custom rules to detect and block open redirect attempts targeting Mayan EDMS endpoints. Enhance user awareness training focusing on phishing risks associated with URL redirection and encourage verification of URLs before clicking. Monitor logs for unusual redirect patterns or spikes in authentication-related requests. Coordinate with IT security teams to conduct penetration testing and vulnerability scanning specifically targeting open redirect vectors. Finally, stay informed about backported patches from the vendor and apply them promptly to maintain security across all supported versions.
