Summary
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.
Risk Assessment
The organization is at risk of credential and secret key theft, which could lead to unauthorized system access and further attacks on the infrastructure.
Recommendation
Immediately apply the security patch provided by the vendor and audit the login.pl and debug.pl scripts to implement input validation and parameterized SQL queries.
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-2026-50110Critical
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.
- CVE-2026-50040Medium
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.
Original NVD description (English source)
Storage Concentrator (SC & SCVM) is vulnerable to SQL injection through cookie values processed by the login.pl and debug.pl scripts. The cookie value is incorporated directly into database queries without adequate sanitization, allowing an unauthenticated remote attacker to manipulate those queries and extract sensitive information from the underlying database, including session tokens, password hashes, and stored secret keys.
