Description Summary:
A critical remote code execution vulnerability exists in the filemanager.php component of Alexantr filemanager v.1.0, allowing unauthenticated attackers to execute arbitrary system commands.
Executive Summary:
A critical remote code execution vulnerability in Alexantr filemanager v.1.0 permits unauthenticated attackers to gain full control of the host server.
Vulnerability Details
CVE-ID: CVE-2026-37637
Affected Software: Alexantr filemanager
Affected Versions: v.1.0
Vulnerability: The vulnerability resides in the filemanager.php file, which fails to adequately sanitize user input, enabling an unauthenticated remote attacker to inject and execute arbitrary code. This flaw allows for complete system compromise if the file manager is exposed to the internet.
Business Impact
A CVSS score of 9.1 highlights the extreme risk associated with this vulnerability, as it allows for full server takeover, data theft, and lateral movement within the network. The ability to execute arbitrary code without authentication provides an attacker with total control over the affected environment, leading to severe reputational and operational damage.
Remediation Plan
Immediate Action: Discontinue use of Alexantr filemanager v.1.0 immediately or isolate the component from all network access until a security update is applied.
Proactive Monitoring: Inspect server logs for suspicious PHP execution patterns or files created in the web directory that were not authorized by administrative staff.
Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block common code injection attempts targeting file management utilities.
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of Jun 28, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
This vulnerability presents a severe risk to any environment hosting this file manager. Immediate removal or patching is required to prevent unauthorized system access. Security teams should prioritize identifying any instances of this software within their infrastructure and ensuring they are either updated or decommissioned.
