# CVE-2026-2584: SQL Injection in Ciser System SL firmware

- Severity: CVSS 9.3 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:L/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-03-02 · Updated: 2026-03-02

## Affected

- Ciser System SL CSIP firmware: 3.0 to 5.1

## Description

A critical SQL Injection (SQLi) vulnerability has been identified in the authentication module of the system. An unauthenticated, remote attacker (AV:N/PR:N) can exploit this flaw by sending specially crafted SQL queries through the login interface. Due to low attack complexity (AC:L) and the absence of specific requirements (AT:N), the vulnerability allows for a total compromise of the system's configuration data (VC:H/VI:H). While the availability of the service remains unaffected (VA:N), the breach may lead to a limited exposure of sensitive information regarding subsequent or interconnected systems (SC:L).
