Overview<\/strong><\/p>\n

In this blog post, we are going to dive deep into a critical security vulnerability identified as CVE-2025-55746 that affects Directus, a real-time API and App dashboard for managing SQL database content. This vulnerability, if exploited, can lead to significant system compromise or data leakage, impacting the integrity and confidentiality of the targeted system. The wide usage and critical nature of Directus in managing database content makes this vulnerability a high-risk<\/a> concern for organizations across sectors.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-55746
\nSeverity: Critical (CVSS: 9.3)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise or data leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Directus | 10.8.0 to before 11.9.3<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability lies in the file<\/a> update mechanism of Directus. An unauthenticated actor can exploit this vulnerability<\/a> to modify existing files with arbitrary contents, without changes being applied to the files’ database-resident metadata. In addition, the actor can upload new files<\/a> with any content and extensions, which won’t show up in the Directus UI. This allows the attacker to inject malicious code or scripts into the system, which can potentially lead to system<\/a> compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited using a malicious HTTP request:<\/a><\/p>\n

POST \/file\/update HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/octet-stream\n{ \"file_content\": \"<script>malicious_script<\/script>\", \"file_extension\": \".html\" }<\/code><\/pre>\n
In this example, the attacker sends a POST request to the ‘\/file\/update’ endpoint of the vulnerable Directus version<\/a>. The request contains a malicious script as the file content and specifies the file extension<\/a> as ‘.html. This leads to the injection of the malicious script into the system, potentially leading<\/a> to system compromise.<\/p>\n
Mitigation Measures<\/strong><\/p>\n
The most effective way to mitigate this vulnerability is by applying the vendor patch. Directus has released version 11.9.3, which addresses this vulnerability<\/a>. If for some reason, patching is not an immediate option, a WAF (Web Application Firewall) or IDS (Intrusion Detection System) can be used as a temporary mitigation measure. These systems can help detect and block malicious traffic, therefore reducing the likelihood of successful exploitation. However, they do not eliminate the vulnerability and are not a substitute for patching. It is strongly recommended to apply the vendor patch as soon as possible.<\/p>\n","protected":false},"excerpt":{"rendered":"
