KL-001-2025-012: Xorux XorMon-NG Read Only User Export Device Configuration Exposing Sensitive Information

Title: Xorux XorMon-NG Read Only User Export Device Configuration Exposing Sensitive Information
Advisory ID: KL-001-2025-012
Publication Date: 2025-07-28
Publication URL: https://korelogic.com/Resources/Advisories/KL-001-2025-012.txt


1. Vulnerability Details

      Affected Vendor: Xorux
      Affected Product: XorMon-NG
      Affected Version: 1.8 and prior
      Platform: Debian
      CWE Classification: CWE-648: Incorrect Use of Privileged APIs
      CVE ID: CVE-2025-54766


2. Vulnerability Description

      An API endpoint that should be limited to web application
      administrators is hidden from, but accessible by, lower-level
      read only web application users. The endpoint can be used
      to export the appliance configuration, exposing sensitive
      information.


3. Technical Description

      A read-only user can access a web application endpoint by
      which device exports can be downloaded. The device exports
      are in tar.gz.gpg format, and can be extracted to reveal
      sensitive information that a read-only user should not be
      privileged to view. The GPG decryption uses a default of
      "undefined" for symmetric encryption and decryption. These
      files include password hashes for all users within the
      Xormon-NG web application and cloud credentials in clear
      text. An authenticated, read-only attacker could leverage
      this vulnerability to obtain and attempt to crack password
      hashes for more privileged users, including the admin user. An
      attacker could also leverage this vulnerability to gain access
      to cloud infrastructure.


4. Mitigation and Remediation Recommendation

      Xorux released version 1.9.38, which includes a remediation
      for this vulnerability. See https://xormon.com/note190.php.
