NVD · unedited
TR1200 v2.4.15, TR3000 v2.4.21, WR300 v2.4.25, WR1200 v2.4.23, WR1300 v2.4.22, WR1500 v2.3.10, WR3000 v2.4.19, WR3600 v2.3.16, and WR6500 v2.3.15 were discovered to contain a command injection vulnerability in the system.setclock interface. This vulnerability allows attackers to execute arbitrary commands as root via a crafted input.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidence
Multiple router firmware versions across TR and WR product lines contain a command injection vulnerability in the system.setclock interface. Attackers can inject and execute arbitrary operating system commands with root privileges, achieving full device compromise without authentication.
MitigationApply vendor firmware updates when available. As an interim measure, restrict network access to the system.setclock interface and monitor for suspicious clock configuration requests.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Identify router model and firmware version
Access the device web interface or check the admin/settings page for firmware version information, or use SNMP/SSH to query the device if available
Affected if The device is a TR1200 with firmware between v2.4.15 and unknown upper bound, or a WR6500 with firmware between v2.0.0 and v2.3.15, or any model in the TR1200 to WR6500 product line within these version ranges
Confirm system.setclock interface exists
Attempt to access the system.setclock API endpoint via HTTP/HTTPS request (e.g., POST to /cgi-bin/system.setclock or similar path; consult vendor documentation for exact endpoint)
Affected if The endpoint responds and accepts input, indicating the vulnerable interface is present on the device
Verify interface is network-accessible
From an external network perspective, test connectivity to the device management port (typically HTTP port 80 or HTTPS port 443) and attempt to reach the system.setclock endpoint without authentication
Affected if The management interface and vulnerable endpoint are exposed to the network without authentication barriers
Check for signs of compromise
Review device logs for unexpected commands, new user accounts, or modified configurations. Look for unusual network outbound connections or processes. Compare current configuration against known-good backups
Affected if Logs or configuration show unexpected commands, new administrative accounts, or configuration changes not initiated by legitimate administrators
The device is affected if it is a TR1200 or WR6500 router (or related model) running firmware within v2.4.15 to v2.3.15 range and the system.setclock interface is accessible without authentication.

CVE-2026-38798 is a command injection flaw in the setclock interface — the clock synchronization function on embedded networking firmware. That framing sells it short. The critical detail is that setclock almost certainly invokes external binaries like 'date' or 'busybox date' with shell-expanded arguments, meaning the vulnerability is either direct shell metacharacter injection or command substitution via backticks and $() in how user input flows through to the system clock utility.
Here's what makes this different from typical command injection: compromising the clock doesn't just give you root, it gives you full control over the device's temporal reality. That breaks three things simultaneously. Certificate validation — rollback the clock and you can present a cert that was valid years ago, defeating TLS verification on backends that haven't revoked it. Authentication timers — manipulate session timestamps to extend validity or replay old tokens. Log forensics — backdate system events to cover your tracks or selectively erase entries.
This is a persistence-capability exploit disguised as an entry point. The EPSS score of 0.02619 reflects current exploitation activity, not potential. Firmware vulnerabilities in deployed devices have a shelf life measured in years, not weeks.
Your priorities: First, determine whether setclock is exposed unauthenticated — if it is, this is a different severity conversation entirely. Second, audit the firmware changelog to understand when this was introduced versus when it was fixed, and whether the v2.3.x and v2.4.x branches share the same vulnerable code path or represent parallel development lines. Third, the nine affected models point to a shared codebase component — find that shared library or function, because the same development pattern that produced vulnerable setclock code almost certainly produced it elsewhere. This is the start of a systemic audit, not the end of a one-off patch.
