CVE-2025-12615: Phpgurukul News Portal Auth Bypass Flaw

CVE-2025-12615 Overview

CVE-2025-12615 affects PHPGurukul News Portal 1.0, a Python/Django-based news management application. The vulnerability resides in the /onps/settings.py configuration file, where the SECRET_KEY parameter is hard-coded into the source. This weakness is categorized under CWE-320: Key Management Errors. An attacker who obtains the publicly disclosed key can forge cryptographic material that the Django framework treats as authentic. The exploit details have been published, although successful exploitation requires high attack complexity and user interaction.

Critical Impact

A disclosed hard-coded SECRET_KEY enables attackers to forge session cookies, tamper with signed data, and bypass cryptographic protections within Django-based News Portal deployments.

Affected Products

• PHPGurukul News Portal 1.0
• Deployments using the default /onps/settings.py configuration
• Django installations relying on the shipped SECRET_KEY value

Technical Details for CVE-2025-12615

Vulnerability Analysis

The vulnerability stems from a hard-coded cryptographic key embedded in the Django settings file /onps/settings.py. Django uses SECRET_KEY to sign session cookies, password reset tokens, CSRF tokens, and any data passed through the django.core.signing module. When this key ships with the source, every installation of News Portal 1.0 shares the same secret. An attacker who reads the public repository obtains the key without needing access to the target server. The disclosed EPSS score of 0.059% and percentile of 18.253 reflect a low predicted exploitation rate, but the cryptographic guarantees of any deployment using the default key are effectively void.

Root Cause

The root cause is a static SECRET_KEY value committed to the application's source code. Django documentation explicitly warns against storing this value in version control or distributing it with the application. The News Portal project ships the key in /onps/settings.py, meaning operators who deploy the application without rotating the key inherit a publicly known secret.

Attack Vector

An attacker retrieves the hard-coded SECRET_KEY from the public source repository. The attacker then crafts a forged session cookie, password reset token, or other signed payload using the known key. The forged value is submitted to a vulnerable News Portal instance over the network. The application validates the signature against the same key and accepts the attacker-controlled data. Exploitation requires user interaction and depends on the specific Django feature being abused, which raises attack complexity.

No verified proof-of-concept code is published. See the GitHub Documentation on Cryptographic Key for technical details on the affected configuration.

Detection Methods for CVE-2025-12615

Indicators of Compromise

• Unexpected authenticated sessions originating from external IP addresses without corresponding login events in application logs
• Password reset confirmations processed without prior reset requests in the audit trail
• Django SuspiciousOperation or BadSignature exceptions appearing alongside successful requests using signed tokens

Detection Strategies

• Compare the deployed SECRET_KEY value in /onps/settings.py against the upstream repository contents to confirm whether the default key is still in use
• Monitor web server logs for session cookies (sessionid) that decode successfully but lack a prior Set-Cookie issuance event
• Inspect Django logs for cryptographic signing operations on unusual endpoints, particularly auth and signing modules

Monitoring Recommendations

• Centralize Django application logs and alert on anomalies in session creation rates and password reset flows
• Track outbound references to the News Portal source repository from internal networks to identify staff or attackers retrieving the key
• Review CSRF token rejection rates, as forged tokens generated with the public key may produce inconsistent patterns

How to Mitigate CVE-2025-12615

Immediate Actions Required

• Replace the hard-coded SECRET_KEY value in /onps/settings.py with a high-entropy value generated locally and stored outside version control
• Invalidate all existing sessions and force re-authentication after rotating the key
• Audit any signed tokens, password reset links, or cached signed data and regenerate them under the new key

Patch Information

No vendor-supplied patch is referenced in the CVE record. Operators must remediate by rotating the SECRET_KEY manually. Refer to PHP Gurukul Security Resources and VulDB #330909 for vendor and advisory updates.

Workarounds

• Load SECRET_KEY from an environment variable or secrets manager rather than from source code
• Restrict read access to settings.py on the production server using file system permissions
• Place the News Portal application behind authentication-aware reverse proxy controls to limit exposure of signing-dependent endpoints

# Configuration example: load SECRET_KEY from environment
# In /onps/settings.py
import os
SECRET_KEY = os.environ['DJANGO_SECRET_KEY']

# Generate a new key at the shell
python -c "from django.core.management.utils import get_random_secret_key; print(get_random_secret_key())"

# Export it before launching the application
export DJANGO_SECRET_KEY='<generated-value>'
