Detailsinfo

A vulnerability classified as critical has been found in D-Link G416 (the affected version unknown). This affects an unknown part of the component httpd. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

D-Link G416 httpd API-AUTH Digest Processing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link G416 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 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-21662.

The weakness was disclosed 12/20/2023 as ZDI-23-1826. The advisory is shared at zerodayinitiative.com. This vulnerability is uniquely identified as CVE-2023-50210 since 12/05/2023. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/10/2025).
