Yamcs · Yamcs · CVE-2023-45280
**Name of the Vulnerable Software and Affected Versions**
Yamcs version 5.8.6
**Description**
The issue allows for Cross-Site Scripting (XSS) due to the ability to upload arbitrary files, including HTML files containing JavaScript, to the primary storage mechanism, known as a Bucket. An attacker can upload such a file and then navigate to it, causing the browser to execute the arbitrary JavaScript when the file is opened.
**Recommendations**
For Yamcs version 5.8.6, consider restricting the upload of HTML files or files containing JavaScript to the Bucket as a temporary workaround until a patch is available. Additionally, avoid navigating to or opening suspicious files uploaded to the Bucket to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
