| CVE-2026-38819 | 1 Opennds | 1 Opennds | 2026-08-28 | 5.3 Medium |
| Multiple memory leaks in openNDS before 11.0.0 allow an unauthenticated attacker on the captive portal network to exhaust all available memory on the device within minutes. | ||||
| CVE-2026-38820 | 1 Opennds | 1 Opennds | 2026-08-28 | 8.3 High |
| openNDS before 11.0.0 is susceptible to unauthenticated OS command execution via shell command injection through the fas query parameter on the /opennds_preauth/ endpoint because of libopennds.sh. | ||||
| CVE-2026-38822 | 1 Opennds | 1 Opennds | 2026-08-28 | 7.6 High |
| In openNDS before 11.0.0, the client_params.sh script, invoked by the openNDS daemon to serve the authenticated client status page, is vulnerable to OS command injection through crafted HTTP GET query parameter keys. An authenticated captive portal user can inject arbitrary shell commands by embedding semicolons in a URL query parameter name. | ||||
| CVE-2026-38821 | 1 Opennds | 1 Opennds | 2026-08-28 | 7.1 High |
| A heap-based buffer overflow vulnerability exists in openNDS before 11.0.0 that allows an unauthenticated attacker on the captive portal network to crash the openNDS daemon (denial of service) and potentially achieve remote code execution. This is in http_microhttpd.c. | ||||
| CVE-2023-38319 | 1 Opennds | 1 Opennds | 2025-06-20 | 9.8 Critical |
| An issue was discovered in OpenNDS before 10.1.3. It fails to sanitize the FAS key entry in the configuration file, allowing attackers that have direct or indirect access to this file to execute arbitrary OS commands. | ||||
| CVE-2023-38318 | 1 Opennds | 1 Opennds | 2025-06-20 | 9.8 Critical |
| An issue was discovered in OpenNDS before 10.1.3. It fails to sanitize the gateway FQDN entry in the configuration file, allowing attackers that have direct or indirect access to this file to execute arbitrary OS commands. | ||||
| CVE-2023-38317 | 1 Opennds | 1 Opennds | 2025-06-03 | 9.8 Critical |
| An issue was discovered in OpenNDS before 10.1.3. It fails to sanitize the network interface name entry in the configuration file, allowing attackers that have direct or indirect access to this file to execute arbitrary OS commands. | ||||
| CVE-2023-38323 | 1 Opennds | 1 Opennds | 2025-05-29 | 9.8 Critical |
| An issue was discovered in OpenNDS before 10.1.3. It fails to sanitize the status path script entry in the configuration file, allowing attackers that have direct or indirect access to this file to execute arbitrary OS commands. | ||||
| CVE-2024-25763 | 1 Opennds | 1 Opennds | 2025-04-14 | 5.5 Medium |
| openNDS 10.2.0 is vulnerable to Use-After-Free via /openNDS/src/auth.c. | ||||
| CVE-2023-41102 | 1 Opennds | 1 Opennds | 2024-11-21 | 7.5 High |
| An issue was discovered in the captive portal in OpenNDS before version 10.1.3. It has multiple memory leaks due to not freeing up allocated memory. This may lead to a Denial-of-Service condition due to the consumption of all available memory. Affected OpenNDS before version 10.1.3 fixed in OpenWrt master and OpenWrt 23.05 on 23. November by updating OpenNDS to version 10.2.0. | ||||
| CVE-2023-41101 | 1 Opennds | 1 Opennds | 2024-11-21 | 9.8 Critical |
| An issue was discovered in the captive portal in OpenNDS before version 10.1.3. get_query in http_microhttpd.c does not validate the length of the query string of GET requests. This leads to a stack-based buffer overflow in versions 9.x and earlier, and to a heap-based buffer overflow in versions 10.x and later. Attackers may exploit the issue to crash OpenNDS (Denial-of-Service condition) or to inject and execute arbitrary bytecode (Remote Code Execution). Affected OpenNDS before version 10.1.3 fixed in OpenWrt master and OpenWrt 23.05 on 23. November by updating OpenNDS to version 10.2.0. | ||||
