Summary

CVE-2024-0769 is a medium-severity Path Traversal (CWE-22) vulnerability in Dlink Dir-859 Firmware. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.4% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.

CVE-2024-0769 is a path traversal vulnerability, tracked as CWE-22, that affects the unsupported D-Link DIR-859 firmware version 1.06B01. The flaw resides in the HTTP POST Request Handler component within the file /hedwig.cgi, where the service argument can be manipulated with a crafted input such as ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml to traverse directories.

An unauthenticated remote attacker can send a specially formed HTTP POST request to read arbitrary files on the device, resulting in limited information disclosure as reflected in the CVSS 5.3 score. The vulnerability was publicly disclosed with a working exploit and assigned VDB-251666.

D-Link has confirmed the DIR-859 is end-of-life, issued an advisory (SAP10371) stating the product is no longer supported, and recommends immediate retirement and replacement. The EPSS score stands at 0.7676 with no material increase after disclosure.

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.

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

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.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.
