CVE-2024-0769
Published: June 25, 2025
Official Description
D-Link DIR-859 routers contain a path traversal vulnerability in the file /hedwig.cgi of the component HTTP POST Request Handler. Manipulation of the argument service with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml allows for the leakage of session data potentially enabling privilege escalation and unauthorized control of the device. This vulnerability affects legacy D-Link products. All associated hardware revisions have reached their end-of-life (EOL) or end-of-service (EOS) life cycle and should be retired and replaced per vendor instructions.
CISA KEV Advisory
D-Link DIR-859 Router Path Traversal Vulnerability
D-Link DIR-859 routers contain a path traversal vulnerability in the file /hedwig.cgi of the component HTTP POST Request Handler. Manipulation of the argument service with the input ../../../../htdocs/webinc/getcfg/DHCPS6.BRIDGE-1.xml allows for the leakage of session data potentially enabling privilege escalation and unauthorized control of the device. This vulnerability affects legacy D-Link products. All associated hardware revisions have reached their end-of-life (EOL) or end-of-service (EOS) life cycle and should be retired and replaced per vendor instructions.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
D-Link DIR-859 routers have a path traversal vulnerability in the HTTP POST Request Handler, which can lead to session data leakage and potential privilege escalation. The high EPSS score of 0.75239 indicates a significant likelihood of exploitation, and its presence in CISA's KEV confirms active exploitation, making this a critical vulnerability for affected devices.
This vulnerability is actively being exploited in the wild, as confirmed by its inclusion in CISA's KEV. It is remotely exploitable.
D-Link DIR-859 routers have reached end-of-life; affected devices should be retired and replaced with supported hardware as per vendor instructions.
Technical Analysis
CVE-2024-0769 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-0769 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
