Summary
File Browser has a Path-Based Access Control Bypass via Multiple Leading Slashes in URL
Details

Summary

An authenticated user can bypass the application's "Disallow" file path rules by modifying the request URL. By adding multiple slashes (e.g., //private/) to the path, the authorization check fails to match the rule, while the underlying filesystem resolves the path correctly, granting unauthorized access to restricted files.

Details

The vulnerability allows users to bypass "Disallow" rules defined by administrators.

The issue stems from how the application handles URL path normalization and rule matching:

  1. Router Configuration: The router in http/http.go is configured with r.SkipClean(true). This prevents the automatic collapse of multiple slashes (e.g., // becoming /) before the request reaches the handler.
  2. Insecure Rule Matching: The rule enforcement logic in rules/rules.go relies on a simple string prefix match: strings.HasPrefix(path, r.Path). If a rule disallows /private, a request for //private fails this check because //private does not strictly start with /private.
  3. Filesystem Resolution: After bypassing the rule check, the non-normalized path is passed to the filesystem. The filesystem treats the multiple slashes as a single separator, successfully resolving //private/secret.txt and serving the file.

PoC

Python minimal PoC

The following steps demonstrate the vulnerability: 1. Setup: - Admin user creates a folder /private and adds a file /private/secret.txt. Screenshot_20260123_151608 Screenshot_20260123_151551 - Admin adds a Disallow rule for user bob on the path /private. Screenshot_20260123_151502

  1. Verification:
  2. User bob requests GET /api/resources/private/secret.txt.
  3. Server responds: 403 Forbidden. Screenshot_20260123_154446
  4. Exploit:
  5. User bob requests GET /api/resources//private/secret.txt.
  6. Server responds: 200 OK (Bypass successful). Screenshot_20260123_154544 Screenshot_20260123_154618

Impact

This vulnerability impacts the confidentiality and integrity of data stored in filebrowser. - Confidentiality: Users can read files they are explicitly forbidden from accessing. - Integrity: If the user has general write permissions but is restricted from specific directories via rules, they can bypass these restrictions to rename, delete, or modify files.

Vulnerability from github – Published: 2022-01-12 00:01 – Updated: 2022-07-13 00:01
VLAI
Details

An issue was discovered in SysAid ITIL 20.4.74 b10. The /enduserreg endpoint is used to register end users anonymously, but does not respect the server-side setting that determines if anonymous users are allowed to register new accounts. Configuring the server-side setting to disable anonymous user registration only hides the client-side registration form. An attacker can still post registration data to create new accounts without prior authentication.

Severity
5.3 (Medium)

Details

Dreamweaver Desktop versions 21.7 and earlier are affected by an Incorrect Authorization vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
