Openwrt

Path traversal in OpenWrt's cgi-io cgi-download handler (prior to 25.12.5) allows an authenticated administrator to read arbitrary root-readable files - including /etc/shadow - by exploiting a TOCTOU-style authorization flaw where ACL checks occur before path canonicalization. The rpcd session.c ACL matcher uses fnmatch() without FNM_PATHNAME, meaning a wildcard-prefixed ACL entry (e.g., /etc/config/*) can be defeated by appending ../ sequences that pass the ACL check but resolve to an out-of-scope file when open() is called. No public exploit identified at time of analysis; vendor-released patch is available in v25.12.5.

Stored cross-site scripting in OpenWrt's default odhcpd server (all releases prior to 25.12.5) lets a network-adjacent DHCP client inject forged lease records that execute as HTML/JavaScript in a router administrator's browser. The client-supplied DHCPv6 FQDN option 39 (and DHCPv4 option 12) hostname is written unescaped into /tmp/odhcpd.leases, enabling newline injection of attacker-controlled fields that LuCI's Active DHCPv6 Leases page renders via unsafe dom.append. No public exploit is identified at time of analysis, and the flaw is not in CISA KEV; it is fixed in 25.12.5.

Integer underflow in the OpenWrt Emergency Access Daemon crashes the daemon when any unauthenticated attacker on the local network sends a single crafted UDP packet to it. Affected are all OpenWrt versions prior to v25.12.5. The CVSS adjacent-network vector (AV:A) constrains the attack surface to local or adjacent network segments, but within that context exploitation requires no credentials and no user interaction - a single malformed packet suffices. No public exploit code or CISA KEV listing has been identified at time of analysis; the patch is confirmed available in v25.12.5.

A stored cross-site scripting (XSS) vulnerability exists in the OpenWrt LuCI web interface where malicious JavaScript code embedded in Wi-Fi network names (SSIDs) can execute when users open the wireless scan modal. The vulnerability affects OpenWrt versions newer than 23.05/22.03 up to 24.10.5 and 25.12.0, allowing attackers within wireless range to compromise users who scan for available networks. No active exploitation has been reported (not in KEV), and with an EPSS score not provided, the real-world exploitation risk appears limited despite the high CVSS score of 8.6.

OpenWrt versions prior to 24.10.6 allow local attackers with limited privileges to inject a malicious PATH environment variable into hotplug scripts due to improper filtering in the hotplug_call function, enabling execution of arbitrary binaries with elevated privileges. The vulnerability stems from a strcmp/strncmp logic error that fails to properly exclude the PATH variable when executing scripts in /etc/hotplug.d, resulting in local privilege escalation. No patch is currently available.

A security vulnerability in versions (CVSS 4.9). Remediation should follow standard vulnerability management procedures.

Remote code execution in OpenWrt's mDNS daemon (versions before 24.10.6 and 25.12.1) allows unauthenticated attackers to overflow a 46-byte stack buffer by sending malformed IPv6 PTR queries over multicast DNS on UDP port 5353. The vulnerability stems from insufficient validation of domain name length before copying to a fixed-size buffer, enabling arbitrary code execution on affected embedded devices. No patch is currently available.

Remote code execution in OpenWrt mdns daemon (versions before 24.10.6 and 25.12.1) allows unauthenticated attackers to crash the service or execute arbitrary code by sending specially crafted DNS PTR queries to UDP port 5353, exploiting a stack buffer overflow in the parse_question function. The vulnerability occurs when domain names are expanded and copied without bounds checking, with non-printable characters inflating the payload beyond the fixed 256-byte buffer. No patch is currently available for affected embedded device deployments.

Device unique identifiers in the preloader of Openwrt, Android, Yocto, RDK-B, and Zephyr can be read by attackers with physical access due to a logic error, leading to local information disclosure without requiring additional privileges or user interaction. This vulnerability affects multiple embedded and IoT platforms where the preloader executes before operating system initialization. No patch is currently available for this issue.

OpenWrt and its Software Development Kit contain an out-of-bounds write vulnerability in the WLAN access point firmware caused by improper bounds checking, enabling adjacent network attackers to achieve privilege escalation without user interaction or special privileges. The vulnerability carries high severity with complete impact across confidentiality, integrity, and availability, though no patch is currently available.

An uncaught exception in WLAN AP/STA firmware for NBIoT SDK, OpenWrt, and related development kits enables adjacent network attackers to trigger a denial of service condition that renders the system unresponsive without requiring authentication or user interaction. The vulnerability affects multiple wireless products and has no available patch at this time, presenting a medium-severity risk in networked environments.

OpenWRT and related SDKs are vulnerable to a heap buffer overflow in the WLAN component that allows adjacent network attackers to execute privilege escalation without user interaction or special permissions. The out-of-bounds write condition enables attackers on the same network segment to gain elevated system privileges. No patch is currently available for this vulnerability.

In aee daemon, there is a possible system crash due to a race condition. This could lead to local denial of service if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10190802; Issue ID: MSV-4833.
