CVE-2024-22628 is a high-severity SQL Injection vulnerability affecting the Budget and Expense Tracker System version 1.0. The vulnerability exists in the web application's administrative interface, specifically in the /expense_budget/admin/?page=reports/budget endpoint, where the parameters date_start and date_end are used. An attacker with high privileges (PR:H) can exploit this vulnerability remotely (AV:N) without requiring user interaction (UI:N). The vulnerability allows an attacker to inject malicious SQL code due to insufficient input sanitization or parameterized query usage, leading to unauthorized access and manipulation of the underlying database. The impact includes full compromise of confidentiality, integrity, and availability of the affected system's data, as indicated by the CVSS vector (C:H/I:H/A:H). Although no known public exploits have been reported yet, the vulnerability's nature and ease of exploitation make it a critical risk if left unpatched. The vulnerability is classified under CWE-89, which corresponds to SQL Injection flaws, a common and dangerous web application security issue. No vendor or product-specific details beyond the application name and version are provided, and no patches have been linked yet, indicating that organizations using this software should urgently assess and mitigate this risk.

For European organizations using the Budget and Expense Tracker System v1.0, this vulnerability poses a significant threat. Exploitation could lead to unauthorized disclosure of sensitive financial data, manipulation of budget and expense records, and potential disruption of financial operations. This could result in regulatory non-compliance, especially under GDPR, due to exposure of personal or financial data. The integrity of financial reporting could be compromised, leading to erroneous decision-making or financial losses. Availability impacts could disrupt business continuity, affecting accounting and budgeting processes. Given the administrative interface is targeted, attackers with elevated privileges could leverage this vulnerability to escalate access or move laterally within the network. The absence of known exploits in the wild currently provides a window for proactive defense, but the high CVSS score and ease of remote exploitation without user interaction underscore the urgency for European entities to address this vulnerability promptly.

1. Immediate mitigation should include restricting access to the administrative interface to trusted IP addresses or VPNs to limit exposure. 2. Implement web application firewall (WAF) rules specifically designed to detect and block SQL Injection attempts targeting the vulnerable endpoint parameters. 3. Conduct thorough input validation and parameterized query implementation in the affected codebase to eliminate injection vectors. 4. Monitor logs for unusual database query patterns or failed injection attempts to detect early exploitation attempts. 5. If possible, isolate the Budget and Expense Tracker System from critical network segments until a patch or fix is available. 6. Engage with the software vendor or development team to obtain or develop a security patch addressing the vulnerability. 7. Educate administrative users on the risks and encourage the use of strong authentication methods to reduce the risk of privilege escalation. 8. Regularly back up financial data and test restoration procedures to minimize impact in case of a successful attack.
