Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

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.

Description

A flaw has been found in Mayan EDMS up to 4.10.1. The impacted element is an unknown function of the file /authentication/. This manipulation causes open redirect. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 4.10.2 is sufficient to resolve this issue. The affected component should be upgraded. The vendor confirms that this is "[f]ixed in version 4.10.2". Furthermore, that "[b]ackports for older versions in process and will be out as soon as their respective CI pipelines complete."

Impact

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.

Summary

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.
