CVE-2026-44258: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in efwGrp efw4.X
efw4.X is an Enterprise Framework for Web. Prior to 4.08.010, the elfinder_checkRisk function validates target and targets for path traversal and home containment, but does not validate the dst (destination) parameter used by elfinder_paste. An attacker can copy or move files from within the home directory to any arbitrary destination by setting dst to a base64-encoded traversal path. This bypasses the protected=true security control. This vulnerability is fixed in 4.08.010.
AI Analysis
Technical Summary
The vulnerability in efw4.X (versions before 4.08.010) arises because the elfinder_checkRisk function validates 'target' and 'targets' parameters for path traversal and home containment but fails to validate the 'dst' parameter used by elfinder_paste. An attacker can exploit this by setting 'dst' to a base64-encoded traversal path, bypassing the protected=true security control, and moving or copying files from within the home directory to arbitrary locations. This improper neutralization of special elements leads to OS command injection (CWE-78). The vulnerability has a CVSS 4.0 score of 9.3, indicating critical severity. The issue is resolved in efw4.X version 4.08.010.
Potential Impact
Successful exploitation allows an unauthenticated attacker to copy or move files from the protected home directory to arbitrary destinations on the system, bypassing security controls. This can lead to unauthorized file manipulation, potentially compromising system integrity and confidentiality. The vulnerability is rated critical with a CVSS score of 9.3, reflecting high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
This vulnerability is fixed in efw4.X version 4.08.010. Users should upgrade to version 4.08.010 or later to remediate the issue. Patch status is not explicitly confirmed beyond this version update, so verify with the vendor advisory for the latest remediation guidance.
