Security readout for executives and security teams
Plain-English summary
CVE-2016-15030 is an open redirect in Arno0x TwoFactorAuth. A logged-in remote attacker may manipulate the login page's from parameter to redirect users to an unintended site. This mainly creates phishing and trust-abuse risk, not direct system takeover.
Executive priority
Handle as a moderate web trust issue. Prioritize if this component is internet-facing or used in sensitive authentication workflows, but it is not described as direct data theft or remote code execution.
Technical view
The issue is CWE-601 in login/login.php, where the from argument can influence redirect behavior. The CVSS v2 score is 4.0 with network access, low complexity, authenticated access, partial integrity impact, and no confidentiality or availability impact. Version boundaries are unavailable because the product does not use versioning.
Likely exposure
Exposure appears limited to deployments of Arno0x TwoFactorAuth using the affected login/login.php code. The source bundle does not identify affected or fixed versions, CPEs, package names, or downstream products.
Exploitation context
The sources say the attack can be initiated remotely and requires authentication. There is no KEV listing and no cited evidence of active exploitation in the provided bundle.
Researcher notes
The record is sparse: no affected version range, no unaffected release, and no exploit-in-the-wild evidence. Validation should focus on code lineage and redirect handling in login/login.php rather than version strings.
Mitigation direction
- Apply patch 8549ad3cf197095f783643e41333586d6a4d0e54 from the project repository.
- Review the linked pull request and vendor repository guidance before production rollout.
- Inventory any deployed copies because version-based detection is unavailable.
- Monitor authentication flows for suspicious external redirect targets.
Validation and detection
- Identify whether Arno0x TwoFactorAuth is deployed in your environment.
- Compare login/login.php against the referenced patched commit.
- Confirm the login from parameter cannot redirect users to untrusted external destinations.
- Review web logs for unusual redirect destinations tied to login activity.

URL Redirection to Untrusted Site ('Open Redirect')
URL Redirection to Untrusted Site ('Open Redirect') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
