Low risk14th percentile - higher than 14% of all known CVEs
Summary
Storage Concentrator (SC & SCVM) is vulnerable to reflected cross-site scripting due to unsanitized content being echoed back in 404 error pages. An attacker can craft a malicious URL that, when visited by an authenticated user, causes arbitrary script content to execute within the victim's browser session in the context of the application.
Risk Assessment
The risk includes theft of session cookies, redirection of users to malicious sites, or performing unauthorized actions on behalf of the victim, potentially leading to data confidentiality and integrity breaches.
Recommendation
Immediately update Storage Concentrator to the latest patched version and implement input validation and output encoding for all error pages.
Other vulnerabilities in Storage Concentrator
See all- CVE-2026-56415Critical
Storage Concentrator (SC & SCVM) contains a command injection vulnerability in the debug.pl script that is reachable without authentication. A remote attacker can submit a specially crafted HTTP request containing a malicious payload that is processed without adequate input sanitization, resulting in arbitrary command execution with root-level privileges.
- CVE-2026-56413Critical
A command injection vulnerability in the ms_service.pl service of Storage Concentrator (SC & SCVM) allows an unauthenticated remote attacker to execute arbitrary commands with root privileges by sending a specially crafted packet to the default TCP port 9000.
- CVE-2026-55721Critical
SQL injection vulnerability in Storage Concentrator (SC & SCVM) exists through cookie values processed by login.pl and debug.pl scripts. Unsanitized cookie data is directly incorporated into database queries, allowing an unauthenticated remote attacker to manipulate queries and extract sensitive information such as session tokens, password hashes, and stored secret keys.
- CVE-2026-50110Critical
Storage Concentrator (SC & SCVM) contains hardcoded credentials for numerous internal services stored in a configuration file. Although the credentials are encoded, the encoding can be reversed to plaintext.

Storage Concentrator (SC & SCVM) is vulnerable to reflected cross-site scripting due to unsanitized content being echoed back in 404 error pages. An attacker can craft a malicious URL that, when visited by an authenticated user, causes arbitrary script content to execute within the victim's browser session in the context of the application. This could be leveraged to steal session cookies, redirect users, or perform unauthorized actions on behalf of the victim.
