| タイトル | DLink DAP-2695 v2.00RC131 CWE-78 Improper Neutralization of Special Elements used in an OS |
|---|
| 説明 | During the firmware update process, there is a command injection vulnerability in function sub_4174B0 of program httpd. The network data dword_444084 could be propagated to system command execution function and become part of the function parameters. During the propagation process, there is no verification on network data dword_444084. If the hackers control the network data dword_444084, they could inject and execute malicious code. This issue in the firmware update process of Dlink DAP-2695(firmware version:v2.00RC131) allows attackers to execute arbitrary code or cause denial of service via constructing a malicious command and injecting it into network data.
The exploit chain of command injection vulnerability is upload_captival_tar -> sub_417298(dword_444084->dest) -> sub_4174B0(dest->src) -> sprintf(command, 0xFFu, "rm -f /var/captival_tar/%s\n", src) -> system(command) |
