  1. HighCVSS 8.8 EPSS 0.62%

    odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA handler keeps a per-message first lease pointer so multiple IA options in one message reuse the same Reconfigure authentication key. A DHCPv6 REQUEST from an...

  2. HighCVSS 8.7 EPSS 0.40%

    odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. From version 17.01.0 to before version 25.12.3, odhcpd's DHCPv6 IA parser accepts an IA_NA or IA_PD option whose body is shorter than struct dhcpv6_ia_hdr, casts the option header to that full structur...

  3. MediumCVSS 6.9 EPSS 0.11%

    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...

  4. CriticalCVSS 9.4 EPSS 0.62%

    luci-app-lxc contains an ACL inconsistency vulnerability that allows low-privileged authenticated LuCI users to access backend container management routes without proper authorization checks. Attackers can exploit path traversal via /.%2E in the lxc_name parameter to escape conta...

  5. CriticalCVSS 9.4 EPSS 0.62%

    luci-app-openvpn fails to properly validate the instance_name2 parameter during file upload, allowing authenticated users to perform path traversal and write arbitrary files outside the intended directory. Attackers can upload malicious payloads to gain persistent root code execu...

  6. HighCVSS 8.7 EPSS 3.3%

    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.*, whic...

  7. HighCVSS 8.7 EPSS 0.93%

    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 sequenc...

  8. MediumCVSS 5.1 EPSS 0.24%

    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 administr...

  9. MediumCVSS 6.8 EPSS 0.41%

    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 Ja...

  10. HighCVSS 8.7 EPSS 0.56%

    luci-app-banip contains a log parsing vulnerability where the awk-based parser extracts the first IPv4 address from log lines regardless of field position, allowing attackers to inject arbitrary IPs via attacker-controlled fields like usernames. An unauthenticated remote attacker...

  11. CriticalCVSS 9.4 EPSS 1.6%

    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...

  12. HighCVSS 8.7 EPSS 0.36%

    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...

  13. HighCVSS 8.7 EPSS 0.88%

    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 sm...

  14. MediumCVSS 6.5 EPSS 0.68%

    OpenWrt is a Linux operating system targeting embedded devices. Before v25.12.5, an integer underflow in handle_send_a() of the Emergency Access Daemon allows any unauthenticated attacker on the local network to crash the daemon by sending a single crafted UDP packet. The message...
