Exploitation Conditions

Attacker requires network access to the UniFi Play device management interface, which in standard Ubiquiti deployments is accessible on the local network segment where devices are deployed. Exploitation does NOT require authentication (PR:N in CVSS vector), making any network-reachable device vulnerable. Default deployments typically restrict management interfaces to LAN-only access via UniFi controller segmentation, but misconfigurations exposing device management to guest networks, public Wi-Fi segments, or internet-facing interfaces eliminate this protection. No special firmware features or non-default settings required-vulnerability affects default firmware installations. Organizations using VLAN isolation or firewall rules that permit only Un

Impact

The CVSS 9.8 score reflects maximum impact across confidentiality, integrity, and availability with network-based unauthenticated attack vector (AV:N/AC:L/PR:N/UI:N), indicating this is exploitable remotely without credentials. However, real-world risk requires contextualization. The EPSS score of 0.11% (30th percentile) suggests security researchers and threat actors have not prioritized this vulnerability for active exploitation, likely because UniFi Play audio devices represent a narrow attack surface compared to enterprise infrastructure. The vulnerability is NOT listed in CISA KEV, confirming no confirmed active exploitation. SSVC decision factors: exploitation status is none/proof-of-concept absent, automatable is yes (network reachable, no auth), technical impact is total (RCE). The attack requires network access to the 'UniFi Play network'-interpretation critical: if this means the device management interface must be exposed (typically LAN-only in default deployments), the practical attack surface shrinks dramatically compared to internet-facing services. Priority should be medium-high for organizations with these devices on exposed networks, lower for air-gapped or strictly LAN-segmented deployments. The responsible disclosure via HackerOne and availability of patches before public disclosure reduces immediate risk.

Exploit ScenarioDerived

An attacker on the same network segment as a UniFi Play device (or with routed access to the device management interface) sends crafted HTTP requests to the firmware's web service or management API, embedding directory traversal sequences in file upload or configuration parameters. The vulnerable firmware processes these malicious paths without sanitization, allowing the attacker to write a web shell, modified startup script, or cron job to /tmp, /etc/init.d, or other writable system directories. On next service restart or scheduled task execution, the injected code runs with system privileges, granting the attacker persistent remote code execution for data exfiltration, lateral movement to other network devices, or deployment of additional malware.

Path traversal in UniFi Play PowerAmp (≤1.0.35) and Audio Port (≤1.0.24) firmware allows unauthenticated remote attackers to write arbitrary files for remote code execution. CVSS 9.8 critical severity reflects network-accessible attack requiring no authentication or user interaction. EPSS score of 0.11% (30th percentile) suggests low immediate exploitation probability despite critical rating. No public exploit identified at time of analysis. Reported via HackerOne bug bounty, vendor patches available (PowerAmp 1.0.38+, Audio Port 1.1.9+).

RemediationAI

Vendor-released patches are available: upgrade UniFi Play PowerAmp to firmware version 1.0.38 or later, and upgrade UniFi Play Audio Port to firmware version 1.1.9 or later. Firmware updates should be applied via the UniFi controller interface or device management console following standard Ubiquiti update procedures. Until patching is complete, implement network-level mitigations: restrict access to device management interfaces using firewall rules or VLANs to trusted administrator networks only, disable remote management if not required, and monitor device logs for unusual file write operations or unexpected network connections. Organizations without immediate patching capability should air-gap affected devices from untrusted networks. Detailed update instructions and firmware downloads available in Ubiquiti Security Advisory Bulletin 063: https://community.ui.com/releases/Security-Advisory-Bulletin-063/e468dd4b-5090-4ef8-89d8-939903c08e83. Verify firmware versions post-update and audit network segmentation policies for embedded audio/IoT devices.

Technical ContextAI · show details

This vulnerability exploits CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), commonly known as path traversal or directory traversal. The affected products-Ubiquiti UniFi Play PowerAmp and Audio Port devices-are network-connected audio equipment deployed in commercial and residential installations. The flaw resides in the device firmware's file handling routines, which fail to properly sanitize file path inputs. Attackers can use directory traversal sequences (e.g., '../../../') to escape restricted directories and write files to arbitrary locations on the underlying Linux-based operating system. By writing malicious files to executable paths, startup scripts, or web application directories, attackers can achieve persistent remote code execution with the privileges of the firmware process (likely root or system-level). The CPE identifiers (cpe:2.3:a:ubiquiti_inc:unifi_play_poweramp and cpe:2.3:a:ubiquiti_inc:unifi_play_audio_port) confirm these are embedded device firmwares, not traditional server applications, making filesystem-level access particularly dangerous.

DescriptionCVE.org

A malicious actor with access to the UniFi Play network could exploit a Path Traversal vulnerability found in the device firmware to write files on the system that could be used for a remote code execution (RCE).

Affected Products: UniFi Play PowerAmp (Version 1.0.35 and earlier)
UniFi Play Audio Port  (Version 1.0.24 and earlier) Mitigation: Update UniFi Play PowerAmp to Version 1.0.38 or later
Update UniFi Play Audio Port  to Version 1.1.9 or later

Executive ViewAI

Why It Matters

UniFi Play PowerAmp and Audio Port devices running vulnerable firmware versions can be remotely compromised without authentication, allowing attackers to execute arbitrary code through path traversal file write capabilities. This affects any organization deploying these Ubiquiti audio devices in networked environments and poses direct risk to device integrity and potential lateral network access.

Business Impact: High
Compensating Controls

Apply vendor patch. Until patches are applied: (1) Restrict network access to affected devices via firewall rules, blocking inbound traffic from untrusted networks; (2) Implement network segmentation isolating audio devices on dedicated VLAN with minimal inter-VLAN routing; (3) Monitor device logs for suspicious file write attempts or unexpected process execution; (4) Disable remote management features if available and not operationally required.

Attack Technique

Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
