D-Link: security record
CISA's Known Exploited Vulnerabilities catalog lists 26 flaws in D-Link routers and network gear, cameras and video recorders and home storage and media servers that attackers have exploited in the wild, added between 3 November 2021 and 24 April 2026. CISA marks 2 as known to have been used in ransomware campaigns.
What this list means
CISA adds a flaw to its Known Exploited Vulnerabilities catalog when there is reliable evidence that attackers have used it in the wild and clear steps exist to fix or reduce it. A listed flaw usually has a patch or workaround from the maker. Some older devices are no longer supported and will not be fixed. If you own an affected model, check the maker's notice, update the firmware or replace the device if it is out of support.
D-Link DIR-823X Command Injection Vulnerability
D-Link DIR-823X contains a command injection vulnerability that allows an authorized attacker to execute arbitrary commands on remote devices by sending a POST request to /goform/set_prohibiting via the corresponding function. The impacted product could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
D-Link Routers Buffer Overflow Vulnerability

D-Link DCS-2530L and DCS-2670L devices contains a command injection vulnerability in the cgi-bin/ddns_enc.cgi. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
D-Link DNR-322L Download of Code Without Integrity Check Vulnerability
D-Link DNR-322L contains a download of code without integrity check vulnerability that could allow an authenticated attacker to execute OS level commands on the device. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
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.
D-Link DIR-820 Router OS Command Injection Vulnerability
D-Link DIR-820 routers contain an OS command injection vulnerability that allows a remote, unauthenticated attacker to escalate privileges to root via a crafted payload with the ping_addr parameter to ping.ccp.
D-Link DIR-605 Router Information Disclosure Vulnerability
D-Link DIR-605 routers contain an information disclosure vulnerability that allows attackers to obtain a username and password by forging a post request to the /getcfg.php page.
D-Link DIR-600 Router Cross-Site Request Forgery (CSRF) Vulnerability
D-Link DIR-600 routers contain a cross-site request forgery (CSRF) vulnerability that allows an attacker to change router configurations by hijacking an existing administrator session.
D-Link Multiple NAS Devices Command Injection Vulnerability
D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L contain a command injection vulnerability. When combined with CVE-2024-3272, this can lead to remote, unauthorized code execution.
D-Link Multiple NAS Devices Use of Hard-Coded Credentials Vulnerability
D-Link DNS-320L, DNS-325, DNS-327L, and DNS-340L contains a hard-coded credential that allows an attacker to conduct authenticated command injection, leading to remote, unauthorized code execution.
D-Link DSL-2750B Devices Command Injection Vulnerability
D-Link DSL-2750B devices contain a command injection vulnerability that allows remote, unauthenticated command injection via the login.cgi cli parameter.
D-Link DIR-859 Router Command Execution Vulnerability
D-Link DIR-859 router contains a command execution vulnerability in the UPnP endpoint URL, /gena.cgi. Exploitation allows an unauthenticated remote attacker to execute system commands as root by sending a specially crafted HTTP SUBSCRIBE request to the UPnP service when connecting to the local network.
D-Link DWL-2600AP Access Point Command Injection Vulnerability
D-Link DWL-2600AP access point contains an authenticated command injection vulnerability via the Save Configuration functionality in the Web interface, using shell metacharacters in the admin.cgi?action=config_save configBackup or downloadServerip parameter.
D-Link DIR-820L Remote Code Execution Vulnerability
D-Link DIR-820L contains an unspecified vulnerability in Device Name parameter in /lan.asp which allows for remote code execution.
D-Link Multiple Routers OS Command Injection Vulnerability
Multiple D-Link routers contain an unspecified vulnerability that allows for execution of OS commands.
D-Link DIR-300 Router Cleartext Storage of a Password Vulnerability
The D-Link DIR-300 router stores cleartext passwords, which allows context-dependent attackers to obtain sensitive information.
D-Link DNS-320 Remote Code Execution Vulnerability
The login_mgr.cgi script in D-Link DNS-320 is vulnerable to remote code execution.
D-Link Multiple Routers Remote Code Execution Vulnerability
A remote code execution vulnerability exists in all series H/W revisions routers via the DDNS function in ncc2 binary file.
D-Link DIR-610 Devices Remote Command Execution
