Linkerd is an open source, ultralight, security-first service mesh for Kubernetes. In affected versions when the application being run by linkerd is susceptible to SSRF, an attacker could potentially trigger a denial-of-service (DoS) attack by making requests to localhost:4191/shutdown. Linkerd could introduce an optional environment variable to control a token that must be passed as a header. Linkerd should reject shutdown requests that do not include this header. This issue has been addressed in release version edge-24.6.2 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Certain models of D-Link wireless routers contain an undisclosed factory testing backdoor. Unauthenticated attackers on the local area network can force the device to enable Telnet service by accessing a specific URL and can log in by using the administrator credentials obtained from analyzing the firmware.

Certain models of D-Link wireless routers have a path traversal vulnerability. Unauthenticated attackers on the same local area network can read arbitrary system files by manipulating the URL.

D-Link D-View executeWmicCmd Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of D-Link D-View. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the executeWmicCmd method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21821.

D-Link D-View Use of Hard-coded Cryptographic Key Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of D-Link D-View. Authentication is not required to exploit this vulnerability. The specific flaw exists within the TokenUtils class. The issue results from a hard-coded cryptographic key. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-21991.

D-Link G416 flupl self Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link G416 wireless routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HTTP service listening on TCP port 80. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21294.

D-Link DIR-3040 prog.cgi websSecurityHandler Memory Leak Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to create a denial-of-service condition on affected installations of D-Link DIR-3040 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the prog.cgi program, which handles HNAP requests made to the lighttpd webserver listening on ports 80 and 443. The issue results from the lack of proper memory management when processing HTTP cookie values. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. . Was ZDI-CAN-21668.

D-Link DIR-2640 HTTP Referer Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2640-US routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within prog.cgi, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21853.
