What is CVE-2025-27610?

CVE-2025-27610 is a critical vulnerability affecting the Rack web application framework, primarily used for building web applications in Ruby. This vulnerability arises within the Rack::Static component, which is responsible for serving static files from a specified root directory. Due to inadequate sanitization of user-supplied paths, it allows attackers to exploit path traversal sequences, potentially accessing sensitive files outside the intended directory. The implications of this vulnerability can be severe, leading to unauthorized access to critical data and systems within an organization.

Technical Details

The vulnerability is characterized by improper handling of encoded path traversal sequences in the Rack::Static module, which fails to restrict access to files strictly under the designated root: directory. This issue can be exploited when attackers are able to construct specific requests that bypass intended restrictions, allowing them to retrieve files that should not be publicly exposed. The vulnerability affects versions prior to 2.2.13, 3.0.14, and 3.1.12, all of which have been patched to address the issue. Organizations are advised to either upgrade to these patched versions or implement mitigative measures such as removing or properly configuring Rack::Static.

Potential impact of CVE-2025-27610

Unauthorized Data Exposure: Attackers can gain access to sensitive files stored within the specified root directory, leading to potential data breaches that could involve personal information, financial records, or proprietary data.
Compromised Application Integrity: By exploiting the vulnerability, attackers may manipulate or replace files serving critical application functionality, undermining the integrity of web applications.
Increased Attack Surface: The existence of this vulnerability could lead to further attacks, such as injecting malicious code or gaining footholds within the web application infrastructure, heightening the risk of larger scale breaches or ransomware infections.

Affected Version(s)

rack < 2.2.13 < 2.2.13

rack >= 3.0, < 3.0.14 < 3.0, 3.0.14

rack >= 3.1, < 3.1.12 < 3.1, 3.1.12
