| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2023-49262 | The authentication mechanism can be bypassed by overflowing the value of the Cookie "authentication" field, provided there is an active user session. | [email protected] | 9.8 | 0.67% | 2024-01-12 | 2026-06-17 |
| CVE-2023-49261 | The "tokenKey" value used in user authorization is visible in the HTML source of the login page. | [email protected] | 7.5 | 0.49% | 2024-01-12 | 2026-06-17 |
| CVE-2023-49260 | An XSS attack can be performed by changing the MOTD banner and pointing the victim to the "terminal_tool.cgi" path. It can be used together with the vulnerability CVE-2023-49255. | [email protected] | 6.1 | 0.32% | 2024-01-12 | 2026-06-17 |
| CVE-2023-49259 | The authentication cookies are generated using an algorithm based on the username, hardcoded secret and the up-time, and can be guessed in a reasonable time. | [email protected] | 7.5 | 0.30% | 2024-01-12 | 2026-06-17 |
| CVE-2023-49258 | User browser may be forced to execute JavaScript and pass the authentication cookie to the attacker leveraging the XSS vulnerability located at "/gui/terminal_tool.cgi" in the "data" parameter. | [email protected] | 6.1 | 0.34% | 2024-01-12 | 2026-06-17 |

| CVE-2021-28152 | Hongdian H8922 3.0.5 devices have an undocumented feature that allows access to a shell as a superuser. To connect, the telnet service is used on port 5188 with the default credentials of root:superzxmn. | [email protected] | 9.8 | 5.18% | 2021-05-06 | 2026-06-16 |
| CVE-2021-28151 | Hongdian H8922 3.0.5 devices allow OS command injection via shell metacharacters into the ip-address (aka Destination) field to the tools.cgi ping command, which is accessible with the username guest and password guest. | [email protected] | 8.8 | 27.91% | 2021-05-06 | 2026-06-16 |
| CVE-2021-28150 | Hongdian H8922 3.0.5 devices allow the unprivileged guest user to read cli.conf (with the administrator password and other sensitive data) via /backup2.cgi. | [email protected] | 5.5 | 2.58% | 2021-05-06 | 2026-06-16 |

The /log_download.cgi log export handler does not validate user input and allows a remote attacker with minimal privileges to download any file from the device by substituting ../ (e.g., ../../etc/passwd) This can be carried out with a web browser by changing the file name accordingly. Upon visiting log_download.cgi?type=../../etc/passwd and logging in, the web server will allow a download of the contents of the /etc/passwd file. | [email protected] | 6.5 | 13.75% | 2021-05-06 | 2026-06-16 |
