FAUCET Score

CVE-2012-10021 is a critical stack-based buffer overflow vulnerability affecting D-Link DIR-605L Wireless N300 Cloud Router firmware versions 1.12 and 1.13. The flaw stems from unsafe sprintf() usage in the getAuthCode() function when processing user-supplied CAPTCHA data. This vulnerability allows a remote, unauthenticated attacker to execute arbitrary code with root privileges on the device. Rated with a CVSS score of 9.8 (Critical), this vulnerability has a network attack vector, low attack complexity, and results in complete compromise of confidentiality, integrity, and availability. Its EPSS score is exceptionally high, indicating a significant likelihood of exploitation. While not listed on the KEV catalog, a Metasploit module exists for this vulnerability, confirming readily available exploit code. Despite its severity and exploit availability, there is no recorded community discussion or media coverage, suggesting it may not be widely tracked by the public.
