CVE-2025-14692 identifies an open redirect vulnerability in the Mayan EDMS document management system, specifically affecting versions 4.10.0 and 4.10.1. The vulnerability is located in an unspecified function within the /authentication/ endpoint, which improperly handles URL redirection parameters. This flaw allows an attacker to craft URLs that redirect users to arbitrary external websites, potentially malicious in nature. The vulnerability can be exploited remotely without any authentication or privileges, but requires user interaction to click on the malicious link. 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), no impact on confidentiality (C:N), low impact on integrity (I:L), and no impact on availability (A:N). The vulnerability does not affect system confidentiality or availability directly but can be leveraged in phishing campaigns or to bypass security controls by redirecting users to attacker-controlled domains. The vendor has released version 4.10.2 to address the issue and is preparing backports for older supported versions. While no active exploitation in the wild has been reported, the availability of proof-of-concept exploits increases the risk of opportunistic attacks. Organizations using affected versions should upgrade promptly to prevent exploitation.

For European organizations, the open redirect vulnerability poses a moderate risk primarily through social engineering and phishing attacks. Attackers can exploit the trusted domain of Mayan EDMS to craft URLs that redirect users to malicious websites, potentially leading to credential theft, malware infection, or further compromise. This is particularly concerning for organizations handling sensitive or regulated documents, as users may be more likely to trust links from their document management system. Although the vulnerability does not directly compromise data confidentiality or system integrity, it can facilitate secondary attacks that do. The impact is heightened in sectors with strict compliance requirements such as finance, healthcare, and government, where phishing attacks can lead to regulatory penalties and reputational damage. The requirement for user interaction limits the scope but does not eliminate risk, especially in environments with less security awareness or where users frequently access external links. The absence of known active exploitation reduces immediate urgency but does not preclude future targeted campaigns.

European organizations should immediately upgrade Mayan EDMS installations to version 4.10.2 or later to remediate the open redirect vulnerability. For environments where immediate upgrade is not feasible, implement strict URL validation and sanitization on the /authentication/ endpoint to block unauthorized redirects. Employ web application firewalls (WAFs) with rules designed to detect and block suspicious redirect patterns. Enhance user awareness training focusing on phishing risks, emphasizing caution when clicking on links, even from trusted internal systems. Monitor logs for unusual redirect requests or patterns indicative of exploitation attempts. Consider implementing multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing. Regularly review and update security policies related to document management and user access. Coordinate with the vendor to obtain backported patches for older versions if upgrading is delayed. Finally, conduct penetration testing and vulnerability scanning to verify the absence of exploitable redirects post-mitigation.
