Description
A vulnerability was determined in oretnom23 php-travel-agency-system. Affected by this issue is some unknown functionality of the file admin/session.php of the component Session Handler. Executing a manipulation of the argument user_id can lead to missing authentication. It is possible to launch the attack remotely. The exploit has been publicly disclosed and may be utilized. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

AI Analysis

Impact

The vulnerability resides in session.php of oretnom23's php-travel-agency-system. A manipulation of the user_id argument bypasses authentication checks, allowing an attacker to create or hijack session data without proper credentials. This results in unauthorized access to the administration functions and potentially full control of the system. The flaw falls under Authentication Bypass (CWE-287) and Missing Authentication (CWE-306).

Affected Systems

The affected system is oretnom23's php-travel-agency-system, accessible through its admin/session.php endpoint. No specific version numbers are provided because the project uses rolling releases, so all current releases are potentially vulnerable until an official fix is released.

Risk and Exploitability

The CVSS score is 6.9, indicating moderate to high severity. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, but it has been publicly disclosed and can be exploited remotely. Without a patch, the risk remains significant, especially for exposed installations. Attackers could gain unauthorized administrative access and perform any actions permitted to an authenticated administrator.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Enforce authentication before any session handling logic, ensuring that only verified users can assign or modify the user_id.
  • Validate and sanitize the user_id parameter to prevent manipulation; use strict type checking and whitelist allowed values.
  • Implement access controls in session.php to restrict direct access, such as placing the file behind additional authentication layers or moving it out of the web root.
  • Monitor authentication logs for suspicious user_id values and abnormal session activity; investigate and block offending IPs.
  • Wait for vendor to release an official patch; until then, apply the temporary access restrictions as a workaround.
