CVE-2024-0527 is a SQL Injection vulnerability identified in CXBSoft Url-shorting versions up to 1.3.1, specifically affecting the /admin/pages/update_go.php file within the HTTP POST Request Handler component. The vulnerability arises from improper sanitization of the 'version' parameter, which can be manipulated by an attacker to inject malicious SQL code. This flaw allows an unauthenticated attacker to execute arbitrary SQL commands on the backend database without requiring user interaction. The vulnerability has been publicly disclosed, but no patch or vendor response has been provided as of the publication date. The CVSS 3.1 base score is 6.3 (medium severity), with the vector indicating that the attack requires network access (AV:A), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact includes potential unauthorized disclosure, modification, or deletion of data, as well as possible disruption of service due to database manipulation. The vulnerability is classified under CWE-89, which is a common and critical injection flaw often exploited to compromise web applications. Given the lack of vendor response and public exploit disclosure, the threat is credible and could be leveraged by attackers targeting installations of CXBSoft Url-shorting, particularly in administrative interfaces where elevated privileges might be accessible.

For European organizations using CXBSoft Url-shorting versions 1.3.0 or 1.3.1, this vulnerability poses a significant risk to data confidentiality, integrity, and availability. Attackers exploiting this flaw could extract sensitive information from backend databases, alter or delete critical data, or cause service outages by corrupting database contents. Since the vulnerability is in an administrative endpoint, successful exploitation could lead to full compromise of the URL shortening service, potentially allowing attackers to redirect users to malicious sites or disrupt business operations. This can have cascading effects on brand reputation, customer trust, and compliance with data protection regulations such as GDPR. Additionally, if the URL shortener is integrated with other internal systems or used for critical communication, the impact could extend beyond the immediate application. The lack of vendor patches increases the urgency for organizations to implement compensating controls to mitigate exposure.

Given the absence of an official patch, European organizations should take immediate steps to mitigate this vulnerability. First, restrict access to the /admin/pages/update_go.php endpoint by IP whitelisting or VPN-only access to limit exposure to trusted administrators. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'version' parameter. Conduct thorough input validation and sanitization on all user-supplied data, especially in administrative modules, as a temporary internal fix if source code access is available. Monitor logs for suspicious POST requests to the vulnerable endpoint and set up alerts for anomalous database queries. Consider disabling or replacing the vulnerable CXBSoft Url-shorting component if feasible until a vendor patch is released. Regularly back up databases and test restoration procedures to minimize impact in case of data corruption. Finally, maintain heightened awareness for any emerging exploits targeting this vulnerability and update incident response plans accordingly.
