CVE-2009-4490

30
FAUCET Score

CVE-2009-4490 describes a vulnerability in mini_httpd versions 1.19 and earlier, where the web server fails to sanitize non-printable characters in log files. This oversight could allow remote attackers to manipulate terminal emulator windows, potentially leading to command execution or file overwrites, by injecting escape sequences into HTTP requests. The vulnerability has a CVSS score of 5.0, indicating a medium severity due to its network-based attack vector and low attack complexity, but with no authentication required. While not listed in CISA's KEV catalog, an exploit for a similar version (1.18) exists on ExploitDB, though there is no evidence of active exploitation, Metasploit modules, or significant community discussion or media coverage.
