CVE-2025-47642 describes an Arbitrary File Access vulnerability affecting Ajar Productions Ajar in5 Embed. This flaw allows attackers to upload files, specifically web shells, to a web server, potentially leading to complete system compromise. Versions of Ajar in5 Embed from 0.0.0 through 3.1.5 are vulnerable. A patch is available in version 3.1.6.
The impact of CVE-2025-47642 is severe. An attacker can leverage this vulnerability to upload a web shell – a malicious script that provides remote command execution capabilities. Successful exploitation grants the attacker complete control over the affected web server. This includes the ability to execute arbitrary code, steal sensitive data (database credentials, user information, configuration files), modify website content, and potentially pivot to other systems within the network. The unrestricted nature of the file upload makes this particularly dangerous, as attackers are not limited to specific file types. The blast radius extends beyond the immediate web server, potentially impacting all connected systems and data.
CVE-2025-47642 was published on 2025-05-23. The vulnerability's critical CVSS score (10) indicates a high probability of exploitation. While no public Proof-of-Concept (POC) exploits have been publicly released as of this writing, the ease of uploading web shells often makes these vulnerabilities attractive targets for automated scanning and exploitation campaigns. The vulnerability is not currently listed on KEV or EPSS, but its severity warrants close monitoring.

The primary mitigation for CVE-2025-47642 is to immediately upgrade Ajar in5 Embed to version 3.1.6 or later. If upgrading is not immediately feasible, consider implementing temporary workarounds. These include restricting file upload types to only those absolutely necessary and implementing strict file size limits. Web Application Firewalls (WAFs) can be configured to detect and block suspicious file uploads, particularly those containing known web shell code patterns. Monitor web server logs for unusual file uploads or execution attempts. After upgrading, confirm the vulnerability is resolved by attempting a file upload with a known malicious payload and verifying it is blocked.
