CVE-2025-27888 Scanner

The Apache Druid software is widely employed for real-time data ingestion, storage, and flexible analytical processing. Commonly used by data-driven organizations, it helps in creating analytics applications that require rapid access to large volumes of immutable data. Apache Druid's main advantage lies in its high scalability and support for complex queries, making it integral to big data environments. The software is typically deployed in a distributed manner across clusters to handle large-scale data processing workloads. Companies across sectors, from tech to finance, rely on Druid for gathering insights from massive datasets. The proactive development and backing by Apache ensure constant enhancements to serve diverse user needs effectively.

The vulnerability identified is a Server-Side Request Forgery (SSRF) which can be exploited to send requests from the vulnerable server to any remote server. If an attacker exploits this vulnerability, they could potentially access internal systems within a network that might not otherwise be exposed to the internet. An SSRF vulnerability often arises when user-supplied input is used to construct URLs or web requests without proper validation or filtering. Apache Druid's improper URL redirection management allows attackers to assume control over the URLs, redirecting commands from the intended recipient to a server of their choice. Such vulnerabilities are critical as they may lead to unauthorized data access, loss of data confidentiality, or even facilitate further server-side vulnerabilities.

The technical aspect of the vulnerability involves the ability to craft URLs within Apache Druid that, when exploited, redirect the request to an unintended server. Through this crafted URL, attackers manage to direct traffic through Druid to possibly malicious external servers without proper authorization checks in place. The Apache Druid's management proxy is the integral part that gets manipulated by the exploit due to its configuration. Given that the proxy is typically enabled by default in Druid's out-of-the-box setup, this vulnerability becomes more pronounced. Attackers could inject arbitrary requests to elicit interactions with external systems, thus exploiting the SSRF vulnerability. Moreover, by leveraging this vulnerability, attackers can launch cross-site request forgery (XSRF) or cross-site scripting (XSS) attacks if the management proxy is not adequately secured.

Exploiting this kind of vulnerability can have serious consequences, especially in environments with sensitive data. Systems could be manipulated to divulge confidential information, aiding attackers in the reconnaissance or additional network breaches. Proper exploitation of the SSRF vulnerability could facilitate XSS or XSRF attacks, severely impacting the integrity of web sessions, leading to information theft or unauthorized actions on behalf of legitimate users. Furthermore, attackers may gain unauthorized access to internal databases, systems, or configurations, exposing businesses to data breaches or significant downtime. The ripple effect of such exploitation could impact user trust, business operations, and compliance requirements due to exposure of private data.
