CVE-2026-38822 (GCVE-0-2026-38822)

Vulnerability from nvd – Published: 2026-08-28 00:12 – Updated: 2026-08-28 00:12

Summary

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.

Severity

7.6 (High)

CVE-2023-41102 (GCVE-0-2023-41102)

Vulnerability from nvd – Published: 2023-11-17 00:00 – Updated: 2024-08-02 18:54

Summary

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.

Severity

CVE-2023-41101 (GCVE-0-2023-41101)

Vulnerability from nvd – Published: 2023-11-17 00:00 – Updated: 2024-09-04 20:17

Summary

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.

Vulnerability from nvd – Published: 2023-11-17 00:00 – Updated: 2024-08-02 17:39

Summary

An issue was discovered in OpenNDS Captive Portal before 10.1.2. it has a do_binauth NULL pointer dereference that can be triggered with a crafted GET HTTP request with a missing client redirect query string parameter. Triggering this issue results in crashing openNDS (a Denial-of-Service condition). The issue occurs when the client is about to be authenticated, and can be triggered only when the BinAuth option is set. Affected OpenNDS Captive Portal before version 10.1.2 fixed infixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on28. August 2023 by updating OpenNDS to version 10.1.3.

CVE-2026-38822 (GCVE-0-2026-38822)

Vulnerability from cvelistv5 – Published: 2026-08-28 00:12 – Updated: 2026-08-28 00:12

Summary

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.

Severity

7.6 (High)
