AI-suggested
European organizations should upgrade LinkAce installations to version 2.4.0 or later, where the SSRF vulnerability is fixed by validating and restricting URLs to prevent requests to internal or private network addresses. Until upgrading is possible, organizations should enforce strict authentication and authorization policies to limit access to trusted users only. Network segmentation and firewall rules should be implemented to restrict outbound HTTP requests from the LinkAce server to only necessary external destinations, blocking requests to internal IP ranges. Monitoring and logging HTTP requests made by the application can help detect suspicious scanning activity. Additionally, applying web application firewalls (WAFs) with SSRF detection capabilities can provide an extra layer of defense. Regularly reviewing and auditing user permissions and access logs will further reduce the risk of exploitation.
Description
LinkAce is a self-hosted archive to collect website links. In versions 2.3.0 and below, the htmlKeywordsFromUrl function in the FetchController class accepts user-provided URLs and makes HTTP requests to them without validating that the destination is not an internal or private network resource. This Server-Side Request Forgery (SSRF) vulnerability allows authenticated attackers to use the application server to perform port scanning and service discovery on internal networks. Practical impact is very limited because the function only extracts content from HTML meta keywords tags, which prevents meaningful data exfiltration from databases, APIs, or cloud metadata endpoints. This issue is fixed in version 2.4.0.
