CVE-2026-62381

CWE-122 22/08/2026
luci-lib-px5g 2040-bit Certificate Signing Heap Buffer Overflow
luci-lib-px5g (LuCI) contains a heap-based buffer overflow in the native ASN.1 encoding routine asn1_add_obj (x509write.c) when signing a certificate with a 2040-bit RSA key. For a 255-byte signature, the BIT STRING allocation is computed from the DER length encoding of 255 bytes, but the payload written after prepending the unused-bits byte is 256 bytes, requiring one additional DER length octet. As a result the allocation is 259 bytes while the tag, length, unused-bits byte, and signature require 260 bytes, and the final memcpy writes one byte beyond the heap buffer. The overflow is reachable through the exported Lua interface via create_selfsigned(); whether it is remotely exploitable depends on the embedding application. The vulnerable code is present on the openwrt-18.06 through openwrt-25.12 release branches and is absent from master, where the luci-lib-px5g package has been removed rather than patched.

CWE-78 03/08/2026
OpenWrt luci-app-dockerman Read ACL Remote Code Execution
OpenWrt luci-app-dockerman (LuCI master and openwrt-25.12 snapshots containing the ucode docker_rpc.uc RPC backend after the JS/ucode conversion) contains an OS command injection vulnerability. The package's read ACL grants broad ubus access to docker.* / docker.container.*, which exposes the docker.container.ttyd_start method even though it performs mutating operations. The run_ttyd handler builds a shell command from the request-controlled id, cmd, and uid fields and passes it to system() without quoting or argv-style execution in the rpcd root context. An authenticated attacker holding only the luci-app-dockerman read ACL can inject shell metacharacters (e.g., in id) to execute arbitrary commands as root via an HTTP POST to /ubus. openwrt-24.10 and openwrt-23.05 do not contain this backend and are not affected; no patched version was known as of the advisory.

OpenWrt luci-app-bmx7 Path Traversal via bmx7-info
OpenWrt luci-app-bmx7 before commit 5890760a454dad2cb00389dba2cdc5e779e0ffdd contains a path traversal vulnerability in the bmx7-info CGI script that allows unauthenticated attackers to read files outside the configured runtimeDir. Attackers can supply directory traversal sequences in the query string to escape the intended directory and read sensitive files accessible to the CGI process.

CWE-79 02/08/2026
luci-app-adblock-fast before 1.2.4-4 Stored XSS via file_url.name
luci-app-adblock-fast before 1.2.4-4 contains a stored cross-site scripting vulnerability in the blocklist name field that allows lower-privileged users to inject active HTML. When an administrator views the AdBlock Fast status page, the injected payload executes in the administrator's browser under the LuCI origin.

CWE-79 01/08/2026
luci-app-https-dns-proxy Stored XSS via resolver_url
luci-app-https-dns-proxy contains a stored cross-site scripting vulnerability in the resolver_url parameter that allows authenticated users to inject active HTML. When an administrator views the HTTPS DNS Proxy status page, the resolver URL is rendered as raw HTML and executes JavaScript in the administrator's browser origin.

CWE-79 12/07/2026
LuCI DHCPv6 Lease Hostname Stored Cross-Site Scripting
LuCI versions fail to properly encode DHCPv6 lease hostnames before rendering in status tables, allowing adjacent network attackers to inject HTML markup. Attackers can send a DHCPv6 Client FQDN containing script tags that execute in the administrator's browser when viewing DHCP lease pages.

CWE-79 12/07/2026
luci-app-upnp Stored XSS via UPnP Port Mapping Description
luci-app-upnp contains a stored cross-site scripting vulnerability that allows unauthenticated LAN clients to inject JavaScript via UPnP IGD AddPortMapping SOAP requests. Attackers can send malicious HTML in the NewPortMappingDescription field, which miniupnpd stores and luci-app-upnp renders without output encoding, executing the payload when administrators view the UPnP or Status pages.

CWE-269 12/07/2026
OpenWrt luci-app-samba4 read ACL remote code execution via smbd
OpenWrt luci-app-samba4 read ACL grants file.exec permission on /usr/sbin/smbd, allowing authenticated delegated users to execute the Samba daemon with caller-controlled command-line arguments. Attackers can pass arbitrary Samba global options such as message command to a root smbd process, triggering command execution when SMB protocol messages are processed.

LuCI luci-mod-network: Possible XSS attack in WiFi scan on Joining Wireless Client modal
LuCI is the OpenWrt Configuration Interface. Versions prior to both 24.10.5 and 25.12.0, contain a stored XSS vulnerability in the wireless scan modal, where SSID values from scan results are rendered as raw HTML without any sanitization. The wireless.js file in the luci-mod-network package passes SSIDs via a template literal to dom.append(), which processes them through innerHTML, allowing an attacker to craft a malicious SSID containing arbitrary HTML/JavaScript. Exploitation requires the user to actively open the wireless scan modal (e.g., to connect to a Wi-Fi access point or survey nearby channels), and only affects OpenWrt versions newer than 23.05/22.03 up to the patched releases (24.10.6 and 25.12.1). The issue has been fixed in version LuCI 26.072.65753~068150b.
