Improper authorization in NIH BRICS InET module

IdentifiersCVE-2025-27581CWE-863

CVE-2025-27581 is an improper authorization flaw in NIH BRICS (Biomedical Research Informatics Computing System) through version 14.0.0-67. The issue allows users who do not have the required InET role to access the InET module by sending direct requests to known InET endpoints. This indicates that access control for the module is not consistently enforced server-side for those endpoints, permitting role restrictions to be bypassed when a user targets the underlying URLs directly.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A successful exploit allows an authenticated user without the InET role to gain unauthorized access to functionality within the InET module. Depending on what those exposed endpoints permit, this may result in unauthorized viewing or interaction with module data and features that should be restricted to users assigned the InET role. The available information does not specify whether modification, administrative actions, or further privilege escalation are possible.

Mitigation

If you can’t patch tonight, do this now.

Until a patched version is deployed, restrict access to InET endpoints through compensating controls such as reverse-proxy or application-layer access rules, and monitor for requests to InET URLs from accounts that are not assigned the InET role. Conduct an authorization review of exposed module endpoints and disable or limit access to the InET module where operationally feasible.

Remediation

Patch, then assume compromise.

Upgrade NIH BRICS to a version newer than 14.0.0-67 if a vendor fix is available. Ensure that server-side authorization checks are enforced on every InET endpoint and action, rather than relying on UI-level role restrictions alone. Review all direct-access routes associated with the InET module to confirm that only users with the InET role can reach them.

CVE-2025-27581MaturityOperationalVerified exploit

This repository contains two Bash scripts exploiting CVE-2025-27581, a local privilege escalation vulnerability involving the 'below' utility. The scripts leverage a symlink attack on '/var/log/below/error_root.log' to change permissions on arbitrary files. 'BasicExploit.sh' allows the user to specify any file, attempting to set its permissions to 0666 by exploiting the vulnerability. 'CreateFakeRoot.sh' specifically targets '/etc/passwd', making it world-writable and then appending a new root user entry with a user-supplied password (hashed with SHA-512). This can allow an attacker to gain root access. The exploit requires local access, the ability to run 'below debug dump-store' with sudo, and the ability to manipulate symlinks in the log directory. The repository is structured simply, with two exploit scripts and a README describing their usage and effects.
