Description

CVE-2024-51793 is a critical Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting Webful Creations Computer Repair Shop versions up to 3.8115. This vulnerability allows an attacker to upload a web shell to the web server, potentially leading to remote code execution and complete system compromise. The SOCRadar Vulnerability Risk Score (SVRS) for this CVE is 95, indicating a critical level of severity and the need for immediate action. The high SVRS score highlights that SOCRadar's vulnerability intelligence identifies significant risks associated with CVE-2024-51793 beyond the base CVSS score. The Cybersecurity and Infrastructure Security Agency (CISA) has warned of the vulnerability, calling for immediate and necessary measures. The vulnerability is actively exploited by hackers.

Key Insights

1. Critical Severity: The SVRS of 95 indicates a significantly elevated risk level beyond the CVSS score, implying active exploitation, chatter in dark web forums regarding the exploit, or association with active threat actors.

2. Web Shell Upload: Successful exploitation enables the upload of a web shell, granting the attacker the ability to execute arbitrary code on the server. This can lead to data breaches, system takeover, and further malicious activities. Active exploits have been published.

3. Remote Code Execution: The ability to execute arbitrary code remotely makes this vulnerability a prime target for attackers. It allows them to gain full control over the compromised system, potentially impacting other systems and data within the network.

4. CISA and In the Wild: The Cybersecurity and Infrastructure Security Agency (CISA) has warned of the vulnerability, calling for immediate and necessary measures. The vulnerability is actively exploited by hackers.

Mitigation Strategies

1. Immediate Patching/Upgrade: Upgrade Webful Creations Computer Repair Shop to a version that addresses this vulnerability. If a patch is available, apply it immediately following the vendor's instructions. This is the most effective way to eliminate the vulnerability.

2. File Type Validation: Implement strict file type validation on all file upload functionalities. Only allow explicitly approved file types and reject any others. This prevents the upload of malicious web shells disguised as legitimate files.

3. Input Sanitization: Sanitize all user inputs to prevent malicious code injection. This includes validating and escaping input data to ensure it does not contain executable code or commands.

4. Web Application Firewall (WAF) Rules: Deploy or update WAF rules to detect and block attempts to upload malicious files or exploit this vulnerability. This adds an extra layer of protection even before the traffic reaches the server.
