CVE-2025-25012 is classified as a medium-severity vulnerability affecting Elastic's Kibana. This vulnerability allows URL redirection to an untrusted site, commonly referred to as 'Open Redirect'. It can lead to sending a user to an arbitrary site, potentially resulting in server-side request forgery via a specially crafted URL. With a CVSS score of 4.3, it signifies a moderate level of risk that organizations should not overlook.
The exploitation status of CVE-2025-25012 is currently not confirmed. However, the nature of open redirection vulnerabilities means that attackers may leverage such flaws to redirect users to malicious sites, increasing the risk of phishing attacks or other malicious activities. Therefore, organizations using affected versions of Kibana should prioritize remediation.
Organizations should prioritize patching immediately. It is crucial to recognize the potential impact of this vulnerability on user trust and organizational security posture.
Given that CVE-2025-25012 has a medium exploitability rating, timely action is necessary to protect against possible threats. Organizations should review their Kibana deployments, assess their configurations, and ensure that proper security measures are in place.
Vulnerability Details
The official description for CVE-2025-25012 states that URL redirection to an untrusted site ('Open Redirect') in Kibana can lead to sending a user to an arbitrary site and server-side request forgery via a specially crafted URL. This vulnerability affects Kibana versions starting from 7.0.0 to prior versions of 7.17.29, 8.0.0 to prior versions of 8.17.8, 8.18.0 to prior versions of 8.18.3, and 9.0.0 to prior versions of 9.0.3.
This vulnerability is classified under CWE-601, which pertains to URL Redirection to Untrusted Site. Organizations should take note of the potential for privilege escalation and unauthorized access that could arise from this weakness.
The CVSS score of 4.3 indicates a medium severity level, with the attack vector being network-based. The attack complexity is low, and it requires low privileges, meaning that an attacker could exploit this vulnerability with minimal effort.
Given the potential impacts on integrity and confidentiality, organizations should actively monitor their Kibana deployments for any indicators of exploitation.
Technical Analysis
The root cause of CVE-2025-25012 is a flaw in how Kibana handles URL redirection. This vulnerability allows attackers to craft URLs that redirect users to malicious sites without appropriate validation. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely.
The attack complexity is low, indicating that the exploitation does not require any specialized skill or knowledge. Privileges required are also low, which means even users with minimal permissions could potentially trigger the vulnerability. User interaction is not required, making this vulnerability particularly dangerous as it could be exploited without the victim's knowledge.
The impacts on confidentiality are none, while integrity is impacted due to the potential for unauthorized changes made by an attacker. Availability is also not affected, as the exploitation does not lead to denial of service.
Risk & Impact Analysis
Risk to organizations includes the potential for users to be redirected to malicious sites, leading to phishing attacks and data breaches. The blast radius could extend to any organization using the affected Kibana versions, potentially compromising sensitive data and user trust.
Organizations should assess their exposure to this vulnerability based on their deployment of Kibana and prioritize remediation efforts. Given the medium CVSS score, it is essential to address this vulnerability in the upcoming patch cycle.
The urgency of addressing this vulnerability is moderate. Organizations may schedule remediation efforts as part of their standard security practices.
