A buffer overflow in the httpd daemon on TP-Link TL-WR841N V12 (firmware version 3.16.9) devices allows an authenticated remote attacker to execute arbitrary code via a GET request to the page for the System Tools of the Wi-Fi network. This affects TL-WR841 V12 TL-WR841N(EU)_V12_160624 and TL-WR841 V11 TL-WR841N(EU)_V11_160325 , TL-WR841N_V11_150616 and TL-WR841 V10 TL-WR841N_V10_150310 are also affected.
Security readout for executives and security teams
Plain-English summary
This CVE describes an authenticated buffer overflow in TP-Link TL-WR841-series router web administration software. If an attacker already has valid access to the device interface, the flaw may allow arbitrary code execution. The source bundle does not provide CVSS scoring, patch status, or evidence of active exploitation.
Executive priority
Prioritize remediation for internet-facing, shared-site, or business-critical routers. The business risk is highest where old TP-Link devices remain in production and administrator access is weakly controlled.
Technical view
The issue is reported in the httpd daemon and is reachable through a GET request to a System Tools page in the Wi-Fi network administration interface. Affected builds named in the CVE description include TL-WR841N V12 firmware 3.16.9 and listed V12, V11, and V10 firmware images.
Likely exposure
Exposure is most likely where affected TP-Link TL-WR841/TL-WR841N devices are still deployed and their web administration interface is reachable by users or networks an attacker can access. The vulnerability requires authentication according to the CVE description.
Exploitation context
The source states authenticated remote code execution is possible. The bundle does not include exploit reliability details, weaponization status, or evidence of exploitation in the wild. CISA KEV status is false in the provided data.
Researcher notes
Evidence is limited to the CVE record, CVE List entry, and a Pastebin reference. No CVSS vector, CWE, vendor advisory, patch version, or KEV exploitation signal is present in the supplied bundle.
Mitigation direction
Identify affected TL-WR841/TL-WR841N hardware and firmware versions in inventory.
Check TP-Link advisories and support pages for firmware updates or retirement guidance.
Restrict router administration interfaces to trusted management networks only.
Disable remote administration where it is not strictly required.
Rotate administrative credentials for exposed or shared router interfaces.
Validation and detection
Confirm model, hardware revision, and firmware version on each TP-Link router.
Verify whether administrative web access is reachable from untrusted networks.
Review device logs for unexpected authenticated administration activity.
Document unsupported or unpatchable devices for replacement planning.
