Summary

CVE-2024-6127 is a critical-severity Path Traversal (CWE-22) vulnerability in Aceresponder (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

BC Security Empire versions prior to 5.9.3 contain a path traversal vulnerability, tracked as CVE-2024-6127, that permits remote code execution. The flaw is rooted in improper handling of file paths during agent uploads and is assigned CWE-22 and CWE-434. It carries a CVSS 3.1 score of 9.8, reflecting network-accessible, unauthenticated exploitation with full confidentiality, integrity, and availability impact.

A remote attacker can exploit the issue over HTTP by registering as a legitimate agent, completing the required cryptographic handshakes, and then submitting an upload containing a malicious path that writes attacker-controlled files to arbitrary locations on the server. Successful exploitation grants the attacker the ability to execute arbitrary code on the Empire server.

Public references, including the project changelog and independent advisories, indicate that the issue is resolved in version 5.9.3. Administrators are advised to upgrade immediately and restrict exposure of Empire listeners to trusted networks. The associated EPSS score has remained at 0.6611 since disclosure, and publicly available proof-of-concept code demonstrates straightforward unauthenticated exploitation.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

PR.PS-05 mostly match
prevents

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce allowed file types and processing rules.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.PS-06 partial match
prevents

Secure development practices include input validation and file-type restrictions that prevent this weakness.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
