CVE-2024-49649 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically in the hakeemnala Build App Online product up to version 1.0.23. This vulnerability allows PHP Remote File Inclusion (RFI), where an attacker can manipulate the filename parameter used in PHP's include or require statements to load arbitrary files. This can be exploited to include malicious remote files or local files on the server, leading to arbitrary code execution, data leakage, or full compromise of the web server hosting the application. The root cause is insufficient validation or sanitization of user input controlling the file path in include/require statements. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and documented in the CVE database. The affected product is a web application builder, which likely generates PHP-based web applications, increasing the attack surface. The vulnerability does not require authentication or user interaction, making it easier for remote attackers to exploit. No CVSS score has been assigned yet, but the vulnerability is critical due to the potential for remote code execution and system compromise. The lack of available patches at the time of disclosure increases the urgency for mitigation.

The impact of CVE-2024-49649 on organizations worldwide can be severe. Exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the affected server. This can result in complete compromise of the web server, unauthorized access to sensitive data, defacement of websites, or use of the compromised server as a pivot point for further attacks within the network. Organizations relying on Build App Online for web application development or hosting are at risk of data breaches, service disruption, and reputational damage. The vulnerability's ease of exploitation without authentication increases the likelihood of attacks, especially in environments exposed to the internet. Additionally, attackers could deploy web shells or malware, leading to persistent access and further exploitation. The absence of known exploits currently provides a window for organizations to implement mitigations before widespread attacks occur.

To mitigate CVE-2024-49649, organizations should immediately audit all PHP code generated or managed by Build App Online for unsafe use of include or require statements that incorporate user input. Implement strict input validation and sanitization to ensure only allowed filenames or paths are processed. Employ whitelisting techniques to restrict included files to a predefined set of safe files. Disable allow_url_include in PHP configurations to prevent remote file inclusion. Monitor web server logs for suspicious requests attempting to exploit file inclusion. If possible, isolate affected applications in segmented network zones to limit potential damage. Stay alert for official patches or updates from hakeemnala and apply them promptly once available. Additionally, consider using web application firewalls (WAFs) with rules to detect and block RFI attempts. Conduct regular security assessments and penetration testing focused on file inclusion vulnerabilities.
