CVE-2021-41295
Published: April 11, 2026
Official Description
ECOA BAS controller has a Cross-Site Request Forgery vulnerability, thus authenticated attacker can remotely place a forged request at a malicious web page and execute CRUD commands (GET, POST, PUT, DELETE) to perform arbitrary operations in the system.
Risk Analysis
This Cross-Site Request Forgery (CSRF) vulnerability in ECOA BAS controllers allows an authenticated attacker to execute arbitrary operations on the system. By tricking an authenticated user into visiting a malicious webpage, an attacker can perform CRUD commands. The confirmed exploitation of this vulnerability, as evidenced by its presence in CISA's KEV catalog, makes this a high-priority issue.
This vulnerability is actively exploited in the wild and is included in CISA's Known Exploited Vulnerabilities catalog. Attackers are using forged requests to perform unauthorized operations on the system.
Users of ECOA BAS controllers should apply available patches to address this CSRF vulnerability. Implement strong user awareness training to prevent users from clicking on suspicious links and ensure proper CSRF protection mechanisms are in place.
Technical Analysis
CVE-2021-41295 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2021-41295 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
