CVE-2026-92748: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in BC-SECURITY Empire
BC Security Empire before 6.7.1 fails to validate the multipart filename parameter in upload endpoints, allowing authenticated operators to write files to arbitrary paths on the C2 server. Attackers can use path traversal sequences in the filename to bypass directory containment and write malicious files to sensitive locations for code execution.
AI Analysis
Technical Summary
BC-SECURITY Empire before version 6.7.1 does not properly validate the multipart filename parameter in its upload endpoints. Authenticated users can exploit this by including path traversal sequences in the filename, enabling them to write files outside the intended directory. This improper limitation of pathname to a restricted directory can allow attackers to place malicious files in sensitive locations on the C2 server, potentially leading to code execution.
Potential Impact
An authenticated operator can bypass directory restrictions and write files to arbitrary paths on the server. This can result in placing malicious files in sensitive locations, leading to possible remote code execution. The CVSS 4.0 score of 8.7 (high severity) reflects the network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix is available in BC-SECURITY Empire version 6.7.1. Users should upgrade to version 6.7.1 or later to remediate this vulnerability. No additional mitigations are specified in the provided data.
