Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked in the top 42.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2025-1899 is a critical buffer overflow vulnerability in Tenda TX3 firmware version 16.03.13.11_multi. The flaw affects an unknown functionality within the /goform/setPptpUserList file, where manipulation of the argument list triggers the overflow. It is associated with CWE-119 and CWE-120.
The vulnerability enables remote exploitation by low-privileged users over the network. Per its CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), attacks require network access, low complexity, and low privileges with no user interaction, leading to high availability impact such as denial of service.
Advisories are documented on VulDB at ctiid.298417, id.298417, and submit.506607, with a proof-of-concept exploit publicly disclosed in a GitHub PDF at https://github.com/2664521593/mycve/blob/main/Tenda/TX3/tenda_tx3_bof_5.pdf. The vendor site is at https://www.tenda.com.cn/.
The exploit has been disclosed to the public and may be used against vulnerable devices.
